Jack Wilshere has had that Twitter bio all season to be fair, as soon as he went out on loan he removed any reference to us so that's not really an issue.
It is pretty odd (perhaps even rude!) that he has made no comment about the cup final though - considering he (or whoever does his social media) found time to say happy birthday to his "friend" Cesc bloody Fabregas earlier this month, it's not too much to ask for him to say "Well done lads" is it?!
I don't see him fitting in at Arsenal anymore, he can sod off to West Ham with the rest of "not good enough for a top team" crew.
