Jose Bosingwa has been under fire recently by fans and pundits alike for his recent performances. Is the criticism valid or is he simply being used as a scapegoat for the poor performances of Chelsea? Let’s take a look at the statistics…
This season in all competitions Chelsea have played 36 matches, winning 19, drawing 9, and losing 8 (66 points total using 3 points per win and 1 point per draw as Cup competitions are not allotted points). Of these 36 matches, Jose Bosingwa has played the full 90 minutes in 22 of them.
In these 22 matches, Chelsea have won 9, drawn 8, and lost 5 – an average of 1.59 points per match. In the 14 matches Bosingwa has NOT played the full 90 minutes, Chelsea have won 10, drawn 1, and lost 3, (an average of 2.21 points per match). To put it succinctly, Chelsea are averaging 0.62 points MORE per game when Bosingwa is not on the pitch the entire match, a 39% increase in points.
A pretty alarming statistic, but one could easily say the difference in points could be due to the coincidental lack of offense when Bosingwa was on the pitch – to those arguments I present the following below…
In the 22 matches Bosingwa has played the full 90 minutes in, Chelsea have a +6 goal differential. In the 14 matches Bosingwa has NOT played the full 90 minutes, Chelsea have a +20 goal differential. That’s more than 3 times the goal differential when Bosingwa isn’t on the pitch the entire match.
Chelsea have kept 12 clean sheets this season in 36 matches – in the matches Bosingwa started and finished (22) Chelsea have keep only 4 clean sheets (thus keeping a clean sheet 18% of the time this occurs). In the matches Bosingwa does NOT play from start to finish Chelsea have kept 8 clean sheets in 14 matches, or 57% of the time. Again, a difference of more than three times as much.
Although Bosingwa did not feature in a couple of the Carling Cup and FA Cup matches which Chelsea won handily the difference is so substantial that even if these matches were thrown out the numbers would clearly tell you starting Bosingwa leads to an increase in goals allowed. In addition, given the goal difference discrepancy one could also argue the offense even plays better WITHOUT Bosingwa on the pitch.
While it’s easy to come to the aid of certain players who are under scrutiny there is simply no defense for Jose Bosingwa – he is clearly a defensive liability and his poor play is a key reason why Chelsea continues to struggle this season.
