Northampton – Stoke City in League 2? (Part 1)
Stoke City is famous for their long throw-ins attacking strategy. It is a different kind of attack for the defenders who get used to crosses. It is also a big question for the keepers whether they should stay at the goal line or not. There are some pieces which analyse Stoke’s performance. Is there any other team having the same strategy in English football? Northampton may be the team with similar (or even better) performance in long throw-ins.
Top 5 teams in set play goals in League 2
Considering the number of set play goals, Northampton scored the most set play goals (34 goals). The following table shows the open play and set play goals of 24 League 2 teams this season and highlights the top 5 teams in set play goals. They are AFC Wimbledon, Bradford, Cheltenham, Gillingham and Northampton.
In order to analyse how important set play goals are to different teams, the percentage of set play goals were considered also. The following table shows the percentages of open play and set play goals of 24 League 2 teams this season.
For example, being the League 2 Champion, Gillingham scored 28 set play goals but there were stronger in scoring open play goals. Therefore, set play goals only accounted for 42.4% of their total goals. The top 5 teams with the highest percentage of set play goals were AFC Wimbledon, Aldershot, Bradford, Cheltenham and Northampton. Northampton is the 2nd place in set play goal percentage. 53.1% of their goals were set play goals. Comparing both tables to each other, we can identify that 4 teams existed in the top 5 positions in both tables. They are AFC Wimbledon, Bradford, Cheltenham and Northampton. That means these 4 teams were good at scoring set play goals and set play goals were more important to them. Note that Northampton and AFC Wimbledon are the only two teams scoring more set play goals than open play goals.
Throw-ins goals in League 2
This chart shows how strong Northampton was in throw-in goals. With most of the teams having 3 throw-in goals or less, Northampton scored 13 throw-in goals this season. They scored 100% more than the 4th place Bristol Rovers having 6 throw-in goals. The great difference shows that scoring throw-in goals was a strong weapon of Northampton while most of the teams didn’t have the ability to do so.
If we consider how important throw-in goals are within set play goals, Northampton is still the team showing the highest percentage. 38.24% of their set play goals were throw-in goals. It showed how important throw-in goals were to Northampton.
In fact, Gillingham and Northampton were the only 2 teams with more than 30% of their set play goals as throw-in goals. Considering only 9 teams in the league having more than 10% of their set play goals as throw-in goals, it shows how Northampton outperformed other teams by having 38.24%.
No matter we consider the number of throw-in goals or the percentage of throw-in goals, Northampton is still the best team in the league and they obviously outperformed other teams in the league.
I don’t have the goal scoring data of Stoke City this season. However, I wonder Stoke City can achieve the two conditions of Northampton or not.
- More than 50% of goals were set play goals
- Around 40% of set play goals were throw-in goals
In part 2, the focus will be analysing the details of Northampton’s throw-in goals. It includes when they scored, how they scored, where they scored, where the assists came from, etc.
League 2 2012/13 review: Time Analysis
There were 1411 League 2 goals in the 2012/13 season. This article will focus on the time at which goals were scored during match play. These are important information because it shows the characteristics of different teams. I did a time analysis once in December, 2013. That result showed that there was a systematic and significant upward trend in the number of goals scored as time progressed. This time all the goals in 2012/13 season were included and the upward trend is still the same. It further supports the previous research suggesting an increase in the frequency of goals scored as a match progresses (Jinshan et al., 1993; Reilly, 1996). The methodology is the same as I divided the 90 minutes into six 15-min periods. The following chart shows when the 1411 goals were scored in League 2 this season.
The goals scored in the last 15 minutes of the game were obviously more than other periods.
The following table shows the number of goals scored in six periods of different teams. The data were shown in a Red-Yellow-Green colour scale. That means, the higher number would be highlighted by red and the lower number would be highlighted by green for better visualisation of the data.
Gillingham, Wycombe and Bristol Rovers were the teams which started the game strongly in the first 15 minutes by scoring 14, 13 and 12 goals. Gillingham showed a special characteristic as they scored more goals in first half (39 goals) than second half (27 goals) significantly. They scored least goals in the last quarter (7 goals) which was different from the general trend of other teams which scored most goals in the last quarter. York City was another team having the same characteristic because their first half goals (31) were much more than that in second half (19).
Northampton scored most goals (19) in the last quarter but generally most of the team scored more goals in the last quarter so the difference was not significant. Port Vale showed something special as they significantly outperformed other teams in the second quarter (16-30 mins) by scoring 17 goals while most of the teams had less than 10 goals in this period.
Wycombe was a special team as well because they were particulary strong in the first 15 minutes of the halves by scoring 12 goals in 0-15 and 45-60 minutes. In other periods they scored only 6 to 7 goals.
However, if we just count the goals scored, it is not showing the whole picture of analysis because stronger teams scored more goals (e.g. Port Vale scored 87 goals and Aldershot scored 42 goals). If we want to find the characteristics of the teams, we have to convert these data into percentage which is shown by the following table.
Only 5 teams scored 20% or more goals in the first 15 minutes of the game and they were Aldershot, Bristol Rovers, Gillingham, Wycombe and York City. AFC Wimbledon, Cheltenham and Gillingham were stronger in the 15 minutes before the first half break as they had 22%, 22% and 21% of goals in that period.
Barnet was the weakest team in the first 15 minutes (6%) but they were very strong in the last quarter with 32% scored within the last 15 minutes of the game. Morecambe and Northampton were the two remaining teams which had more than 30% of goals in the last quarter. If we consider the last 30 minutes of the game, the characteristics of these teams were more significant. Barnet and Northampton had 53% and 55% of goals scored in the last 30 minutes of the game and these could be important information for their opponents.
Aldershot and Bristol Rovers shared the same characteristic as they were both strong in the first and last quarters having more than 20% of total number of goals. The team with the most evenly distributed number of goals in all six quarters was Torquay. They had around 15%-18% of goals in each quarter.
To conclude, the characteristics of the teams could be shown by having the time analysis. Some teams were stronger in the first half (e.g. Gillingham and York City). Some teams were stronger in the last 30 minutes of the game (e.g. Barnet and Northampton). These information would be useful for the opposition analysis to know the strengths and weaknesses of the opponents.

Clean Sheets Analysis of League 2
A football game is all about attacking and defending. Therefore, keeping a clean sheet is as important as scoring goals. A team scoring a goal doesn’t guarantee any point but keeping a clean sheet guarantee at least one point and potentially getting three points. In this post, the defensive performance of League 2 teams would be discussed by analysing the clean sheets of League 2. Updated to January 28, there were 338 matches had been played, that means there were 676 team performances. Of these 676 team performances, 189 ended up with a clean sheet (28%). The teams produced 7.88 clean sheets on average. In these 7.88 clean sheets, 5.38 clean sheets led to wins and 2.50 clean sheets led to draws. On the other hand, clean sheets produced about 2.35 points per team and match on average.
The frequency of clean sheets is shown in the following chart.
As shown in the chart, there is a huge range in abilities to keep clean sheets (from 2 to 13). Fleetwood and Cheltenham performed much better than other team, producing 13 and 12 clean sheets. Part of their ability to generate points has been their ability to produce good defence. In the top 4 clean sheet producers (10 teams), only Accrington, Morecambe and Aldershot are in the bottom half of the table. It indicates two results. Firstly, good at keeping clean sheets can lead to good league positions. Secondly, it suggests that defence is not the main issue of the above 3 teams. In order to improve their league positions, they should focus on improving their attacking. Moreover, the bottom 2 clean sheet producers are Bristol Rover, Plymouth and Wimbledon. They are the bottom 3 teams in the League 2 table as well which indicates the importance of keeping clean sheet. On the other hand, it shows how strong Port Vale’s goal scoring was. Port Vale only produced 7 clean sheets which are below average. However, they are at the top of the table which means the high number of goal scored can overcome the weakness of their defence.
Clean sheets were of different value for different teams. This is shown in the following chart.
Clean sheets had enormous value (3 points) for Exeter and Wimbledon. For every single match they held clean sheet, they won the game and got 3 points. Note that Wimbledon is at the bottom of the league table. That means the biggest problem of Wimbledon right now is the defence, not attack. On the other hand, Plymouth had the worst performance in the above chart. It shows that even Plymouth had kept clean sheet, they only managed to 1.5 points on average. Considering both charts, it means that Plymouth is having problems in both attack and defence. In the top 5 teams in this chart, 4 of them are in the top 6 of the league table. In other words, it’s not only keeping clean sheets that’s important, but also how the team managed to get points from clean sheets.
By combining both charts together, the teams can be analysed from another perspective which is shown in the following diagram.
In this chart, the two axes are the two average numbers (2.35 points gained and 7.88 frequencies of clean sheets). The objective of using two average numbers as the axes is to divide 24 teams into four quadrants showing different abilities. Firstly, Bristol Rovers, Plymouth, Torquay and Rochdale are at the bottom left corner. The characteristic of the teams in this quadrant is that they are both weak at producing clean sheets and getting points from clean sheets. The opposite quadrant is the top right quadrant which means the teams were good at producing clean sheets and got points from clean sheets as well. Gillingham was the best performer in this quadrant which means Gillingham had a good balance of attack and defence. On the other hand, the top two performers of keeping clean sheets were in the bottom right quadrant, they should focus on improving their attacking because it was the main issue hindering both teams from getting points from clean sheets. The same argument could be applied to Aldershot and Morecambe as well since they are at the bottom half of the league table. Port Vale didn’t show why they can be the top of league table in this chart because they were weak in producing clean sheets. However, their efficiency is better than Gillingham by getting more points per clean sheet game.
To conclude, keeping clean sheets is a strong indicator of a team’s defending ability. However, it’s not only keeping clean sheets that’s important, but also how the team managed to get points from clean sheets. Therefore, by dividing 24 teams into four quadrants showing different characteristics, we can understand why some teams are doing better than others and which aspects (attacking or defending) should be the main focus point for team improvement.
League 2: How do teams score the first goal?
Last time, I wrote about the importance of the first goal (here). We know how important the first goal is, so the next question is “How can we score it?” Therefore, we will look at how the league 2 teams score their first goals. If you search in the internet, it is not difficult to find some findings about the general goal statistics. However, most of the goals were scored in different backgrounds and situations. Only the first goals are scored under the same circumstances: 0 – 0. Therefore, I think it is meaningful to look at the first goal statistics because it reflects the ability of teams to break the 0 – 0 situation. Please note that all the data of goals and league positions were updated to 22/10/2012.
All First Goals
The following chart shows how the teams scored all their first goals:
The goals were divided into five categories: open play, corner, free kick, penalty and throw-in. Here are the key findings:
- At least 50% of first goals were scored in open play in most teams except Aldershot, Bradford and Gillingham. Only 20% of first goals of Bradford were came from open play.
- Gillingham, which is leading the league, shows how strong they are in this chart. Not only they scored more first goals than the rest of the league, the more important point is they showed that they can score first goal in different ways (the only team which scored first goals in all five categories). They get both quantity and variety of first goals.
- Cheltenham is the second best. They scored 9 first goals in four categories.
- AFC Wimbledon, Bristol Rovers and York City scored all their first goals in open play. If you are play against them, it may be a good idea to be more aggressive in tackling to interrupt their open play because they are weak at scoring the first goal in set piece.
- If we look at the best 4 teams in this chart (Gillingham, Cheltenham, Chesterfield and Rochdale). Their league positions are 1st, 4th, 13th and 8th. I argue that strong at scoring first goal will bring teams to the top half of the table. However, it also depends on how good the team can retain their winning position. This topic was discussed last time.
Open Play First Goals
Then we focus on the open play goals first. The following chart shows how the teams scored the first goals in open play.
The goals were divided into four categories: right foot, left foot, header and other. Here are the key findings:
- Aldershot and Bradford are struggling in scoring open play first goal by scoring just once. However, it is worthy to note that Aldershot is in 23th and Bradford City is in 5th position.
- Barnet and Southend are the second worst by scoring 2 open play first goals. Barnet is in 24th and Southend is in 11th position. I argue that weak at scoring open play first goal will bring the teams to bottom zone but it is interesting to find out what Bradford and Southend did to bring them a decent league position.
- AFC Wimbledon and York City scored the most open play first goal by left foot.
- If we look at the best 5 teams in this chart (Chesterfield, York City, Fleetwood, Morecambe and Port Vale). Their positions are 13th, 12th, 3nd, 14th and 2nd). Only 2 out of 5 teams are in the first 7 positions which is playoff zone. I argue that strong at scoring open play first goal will bring the team to a mid table position at least but not enough to be the top 7 positions.
- Only 8 teams had scored open play first goals by header. 6 out of 8 teams are in the top half of the table. Gillingham and Fleetwood are the best and they are in the top 3 position in the league table. I argue that there is a relationship between them.
Set Piece First Goals
The following chart shows how the teams scored the first goals in set piece.
The goals were divided into four categories: right foot, left foot, header and penalty. Here are the key findings:
- Most of the teams scored 1 or 2 set piece first goal.
- Gillingham is overwhelming in this chart, performing much better than the rest of the league. Interestingly, there is no header and left foot goal within those 7 goals. Scoring set piece first goal is a strong weapon of Gillingham to be the leader of the league.
- Bradford is the strongest team in scoring by headers in set piece first goal.
- If we look at the best 4 teams in this chart (Gillingham, Bradford, Cheltenham and Rochdale). Their league positions are 1st, 5th, 4nd and 8nd). All of them are in top half of the table. 3 out of 4 teams are in the top 7 positions which is playoff zone. I argue that strong at scoring set piece first goal will bring the team to the top 7 positions.
- At least 50% of first goals were scored in open play in most teams except Aldershot, Bradford and Gillingham
- Gillingham and Cheltenham can score first goals through different ways and they are the two best team of scoring first goal
- Strong at scoring first goal will bring teams to the top half of the table
- AFC Wimbledon and York City scored the most open play first goal by left foot
- Only 8 teams had scored open play first goals by header. 6 out of 8 teams are in the top half of the table
- Weak at scoring open play first goal will bring the teams to bottom zone. Aldershot and Barnet are the examples
- Most of the teams scored 1 or 2 set piece first goal
- Gillingham is overwhelming in scoring set piece first goal
- Bradford is the strongest team in scoring by headers in set piece first goal
- Strong at scoring set piece first goal will bring the team to the top 7 positions
Scoring first goal is not everything, it is also important to retain the winning position which was discussed in the last article (here).
