Some people seem to love stats to back up their argument of how good he is.
So
We are 9th in the table for shots on target conceded, Liverpool (243), Man City (235), Arsenal (205), Brighton (190), Villa (182), Tottenham (180), Newcastle (180) and Chelsea (179) have conceded more shots on target, the difference is goals conceded, only Tottenham (49), Liverpool (36), Man City (32), Arsenal (26) and Everton! (48) have conceded less.
We are not even top for shots conceded as some would have you believe, Liverpool (715), Man City (611) and Arsenal (586) are all above us, so that blows the argument that he's behind a crap defence out of the water.
The simple fact is the top four are conceding more shots on target and in general, but they have a much better keeper between the posts capable of stopping them!
