He's a modest, level-headed lad, but he's not going to fill any holes for us that can't be filled by the players we already have (Yedlin for RB, a bunch of players at CB) or by better footballers than him.
Personally I think he should stay at Fiorentina, and as for what we need from this year's bumper crop of free transfers....we should be sprinting towards Fabian Schar as fast as our legs can take us.
I heard a really good interview (on Radio 5) with him a few weeks ago.
He was basically saying that his pace used to make him look a much better player than he was, and he's much happier now having stepped down a level. He was saying he's learning Italian and wants to stay there.
They also talked about his position issue - too small to be a CB, not agile enough to be a FB. He definitely sees himself as a RB though (I suppose we only have 6 of those at the moment).
