On the Y-axis, we have the claims/punches ratio (i.e. A high exit per 90 gives some indication of how dominant the keeper is from set-pieces and crosses. It tells us how many times on average per 90 minutes the keeper exits/leaves his line to go for the ball.

The graph above is a visual representation of adjusted save percentage to goals for all the goalkeepers in the Premier League, some of the world’s best keepers in Europe, and Mendy. * Note the x-axis is inverted with highest goals conceded closer to the left and highest goals conceded closer to the right This suggests that even if Mendy has a dip in performance as a result of playing in a better league or taking time to adjust, he would likely still perform better than Arrizabalaga.Įvaluating Goalkeeper based on Exits per 90 ( number of time the keeper leaves his line to get the ball averaged for 90 mins) and claims/punches ratio /PWfWSh3AGI However, the difference in quality between the goalkeepers based on these metrics is stark. Of course, this is not adjusted for factors such as difference is league competitiveness as the Premier League is arguably a more intense league to be a goalkeeper in. Arrizabalaga was last based on these metrics, suggesting Mendy would be a significant upgrade. ![]() Goalkeeperīased on adjusted save percentage, Mendy would have ranked eighth in the Premier League last season. The adjusted save percentage and GSAA were calculated for all the goalkeepers (see table below). The table above shows the goals, xG goals against and shots against faced by the goalkeepers in the Premier League as well as Mendy’s statistics for his season in France. In order to rank where Mendy would stand in the league for shot-stopping ability, these metrics were calculated for all the Premier League goalkeepers last season. Ranking Mendy in the Premier League Goalkeeper In Mendy’s case that was two percent last season. The aSV% is then calculated by dividing the GSSA over the shots faced on target. Kepa Arrizabalaga, on the other hand, conceded 37 goals compared to his xG conceded of 27.8 giving him a GSSA of -9.16. Mendy conceded 15 goals last season to his xG conceded of 16.37, giving him as GSSA of 1.37. GSSA is the difference between the goals conceded and the xG conceded (based off the quality of shots the keeper had to face). Ted Knutson of Statsbomb devised two metrics to assess shot stopping ability mainly, the goals saved above average (GSSA) and the adjusted save percentage (aSV%). ![]() Three criteria will be used to create a ranking system: shot-stopping ability, behaviour in the boxed based on claim activity, and distribution. In this article, data from last season is used to assess the quality of Chelsea’s new goalkeeper Edouard Mendy. As teams increasingly look to play out from the back and employ a high defensive line, it is important for a goalkeeper to be good with his feet.Ĭontext is everything in football and how “good” a goalkeeper is a function of the team’s preferred playstyle and how the manager sees the role of his goalkeeper, not only in terms of shot-stopping, but also in dominating the box and being part of build-up play. In the modern era, the role of the goalkeeper has evolved from pure shot-stopping one to a range of different roles. How is a keeper’s ability assessed? There are a number of factors that go into evaluating how good a goalkeeper is.
