Damn, this transfer messed the Fellaini Song up...
anyway, good transfer for your side, this guy is very young but extremely talented... technic meets powerness
his strong points are technic, as I said, attacking and defensive header, hiss powerplay (a real box to box mildfielder), his toughness... and I would say that he's a nice, simple and hard working guy
weak points are his feet play in the attacking box (I mean he's not a striker) and he gets too much yellow cards (he has the bad side of his youngness)
so, in my opinion, if he goes on trainning hard and if he stay cool with money, he sould be one of the best Premier League's midfielder
good luck, marouane !
