Off the top of my head, I can remember Paul Robinson (not the fat Spud or the one in Neighbours) taking aim and nailing him recently.
There's an element of that gunnerrr but last season was down to a continued assault on his ankle imo, he'd built up a bit over the sumer and looked pretty solid, his early season form was alright and he looked like gaining some consistency then up stepped Robinson and Essien and he lost any confidence in his ankle after that injury.
@TG as well, I think that's part of why his head ain't right, he doesn't trust his own body any more.
Forgot about the Essien one. I think they repeated it once during the game.
He's turned into The New Diaby™ anyway, so he's got his comeuppance of sorts.
Karma
So...
Walcott (ankle)
Diaby (ankle)
Wilshere (ankle)
Hmmm.
Wenger (face)
It's better to burn out, than to fade away.
