Sad to see my favourite German player join this shower of shit. :(
He will have a huge impact on their midfield. They did decent with Carrick last year and Schweini is easily better...As somone mentioned already he is one of those special players who lifts those around him to another level and he is a great leader/winner.
He didnt play a lot of matches last season, but he was knackered after the long season followed by the World Cup. Unfortunately he will be a great signing if he hits the ground running. I doubt he will have problems adjusting to the PL especially as Van Gaal will give him time to rest/recover in the less important/demanding fixtures.
