Arsenal. SHKODRAN MUSTAFI. 5.0. In place of Calum Chambers midway through the first half, his passing was poor, as always, but his defensive work was strong. And then it happened: Mustafi forgot how to defend. It started by not immediately closing down Abraham, something that his teammates did very well throughout the match, and then continued as he was turned by Abraham in the penalty area who tucked away the winner. Not good.. SUB
