Save Percentage
Mendy currently has an extremely impressive save percentage of 91.7% in all competitions. As he has only played six games for Chelsea, that will almost certainly drop over the course of the season but if you compare it to Kepa Arrizabalaga, there is a huge difference.
The Spaniard only managed to save 57.1% of the shots he faced in his first three Premier League appearances this campaign. That was still better than the 54.5% he managed in the league last season.
