I'm surprised with the criticism he is getting. Yes some control was lost (in the 2nd half more than the first) but I think thats as much down to the structure and how well Schneiderlin played than on Tom.
I thought he was very good yesterday. In the first half he did what he lacked last season, which was have a proper look at the game and almost "play himself in". He made some simple passes, got on the ball, focus on doing the simple things. That then allowed him to carry the ball well, beat players, pick out some more difficult passes and win some important free kicks. If he focusses on the simple things, his natural ability will shine through as he has good vision and can beat a player.
He was poor after half time, but so was the rest of the team. Thats not to say he it's an excuse but I wouldn't single him out for that.
He finished the game more positively and was involved in some good attacking moves.
What was clear to me though, if for a lad to play with the maturity, confidence and composure he has, in the hardest position on the pitch having just turned 20 is very good. It's remarkable clearly and there is not really any players in the league that can be compared to him. I know the lad at Arsenal had some good moments, but he also got badly exposed at other times (more than Tom).
He has come on a lot in the close season. That can and should continue and is all you can ask. He still has a long way to go, but for me he is going the right way.
