Anderson is a player that I really want to make it at United, but as time goes on the more unsure I become that he actually will. When he arrived from Porto he was hailed as an exciting attacking midfielder, for Porto he played as an attacking midfielder and looked a really exciting player.
Since he has come to United though he has often appeared to be lost in midfield, he doesn't seem to have any defined role and I believe this is hampering him. I still belive that he has massive potential but Fergie needs to find him a defined role within the team, a role that he will fill in the majority of games that he plays. He was touted as a possible Scholes replacement, but his game is absolutely nothing like Scholes.
I agree with some of the above that maybe Fergie needs to find a suitable midfield partner for him. Personally I don't know if he is a box-to-box midfielder, an attacking midfielder, a defensive midfielder.
