Defensive Errors comparisonNow I want to investigate the defensive errors and how they may explain some of the goals conceded. As seen from the table, defensive errors can have a massive impact on goals conceded. From the possession stats I see a positive correlation between possession and defensive errors lead to goals. Also, Dangerous play seems to correlate positive with those two factors. However, that could be used to explain that having a great amount of possession means your defence is vulnerable. But this does not mean you have a bad defence. Look at Manchester City, they have a great amount of possession and 6 defensive errors that lead to goal. Manchester City though has the least goals conceded (21) despite being vulnerable to counterattack. This somehow implies that their defence is somehow solid. What this analysis also shows is that Arsenal and Liverpool have some defensive problems which may be due to much pressure or lack of concentration. From this we could say that if the defence of Arsenal and Liverpool were as solid as Manchester City, they would be fairly more competitive. From this graph we see the influence of defensive errors on goals conceded. As seen from this graph, defensive errors have a major impact on goals conceded. Chelsea though stands out, as they only concede 11% of their goals due to defensive errors. Arsenal on the other hand seems to lack concentration in their defensive display as they concede 44,8 % of their goals due to defensive errors.
ConclusionFirst let me start by saying that this analysis should not be considered to be the answer to who is the best and worst teams in the Premier League. Rather, I have tried to explain the trends underlying the defence of the top 7 Premier League teams. However, many conclusions need to be drawn from this analysis. Manchester City, who has conceded the lowest amount of goals must be considered to have the best defence in Premier League. This was shown because they significantly differentiated themselves from the other teams who had high possession. Despite the fact that they concede the third highest amount of goals compared to the other teams, their defence somehow concede the fewest goals in total. What surprises me the most in this analysis is the defensive display of Tottenham. The second part of my analysis showed that Tottenham has the fewest shots against them, both in terms of total shots and shots on target. However, they conceded as many goals as Arsenal. Arsenal has the highest amount of goals conceded due to defensive errors compared to the rest. Liverpool does have the same trends as the Arsenal defence by having many defensive errors and dangerous plays. What my analysis showed in that perspective was that high possession makes your defence vulnerable. From my observations Manchester United also needs to be considered when talking about worst defence in the top 7. They conceded the second highest amount of goals and have had the most shots against them. However, they have not made as many mistakes as Arsenal and Liverpool. This leads me to the conclusion of who has the best defence in the Premier League: Manchester City and surprisingly Tottenham as runner up. In the bottom half is Arsenal and Liverpool which currently must be considered to have the worst defences at the top of Premier League. I hope you found my analysis useful and if you disagree/agree with my analysis, please share your thoughts, since I am open to feedback.
