Wasn't bad at all, and every indication he can ply his trade on the left in the same way he's been getting minutes on the right. Was a bit of an all action performance, with the vast majority being good. Not surprised (and am pleased) that he played his usual game, as opposed to an overly cautiously 'try to get through this without mistakes' kind of game.
Obviously the goal came down his side, but I don't think it's all on him. Don't think Chamberlain did much to help him cover two players there (and this was post-yellow), not to mention the midfielders were slow to drop in for the cross.
Only way he looked his age was his stamina, but he was sprinting up and down the pitch enthusiastically. Shame the ref ruined him being put through by not allowing the advantage. Seem to remember TAA came off on his debut against Spurs with a yellow so he's in good company tonight.
