I think he is a great player, not a complete player yet granted, but he seems to be cutting out the mistakes he was making a lot more at the start of the season (yes I watched the Woolwich game). This is his first season though, it hasn't been a complete season for him yet and I honestly think him playing with Jan, Toby or both will do his career the world of good. Imagine those in a back three, best 2 center backs in the world with a promising 21 year who is very athletic but learning his trade quickly.
He plays out well from the back, he is a great passer of the ball which is apparently one of the reasons we brought him and I honestly think he could be a long term replacement for Toby or Jan.
