#1 David de Gea
Of all the world-class keepers we mentioned so far, De Gea has shipped in the most goals with his club this season. With 21 goals being scored against him, De Gea has conceded the third most goals in the Premier League this season.
To make matters worse, he only has one clean sheet so far, which means to match his tally of 18 clean sheets from last season, he has to block all the attempted shots on his goal in 17 of the remaining 26 fixtures, which is easier said than done.
He conceded at least one goal in each of the UEFA Nations League fixtures, which has prompted fans demanding him being benched in favor of Chelsea keeper Kepa in the future.
Unfortunately for the Atletico Madrid academy product, he can seldom count on his defenders during a match, but his own blunders, like the one that allowed Aguero to double Manchester City's lead last Sunday have let him down.
