It's tough to see him struggle like this.
He has let in some soft goals this season, more near post goals than ever, not saving any penalties, giving up penalties, bad at crosses, fluffing his hands at the ball and missing, running into his own guys in the box, not commanding his box like he once did. Even his kicks aren't going as far as they once did.
Ospina should slot in at Preston as expected, but against Swansea. Is it a decision for Wenger to make or a bit knee jerk from us? Not sure, but the warning signs are pretty glaring.
