It's one of those transfers that would either work out tremendously or be an absolute trainwreck.
Major question marks over his fitness and whether he would work hard enough, but he doesn't get into a Guardiola side until he gets his arse in gear and we've seen him do it for France.
He's a bloody good player when he's in form and if it clicks we could get a world class player on a free. But his problem is massive inconsistency.
I personally wouldn't really judge a player by his perfomances at United. It's a career graveyard and if Pep and the club think they could get a tune out of him, it's an interesting prospect...
The shit stirring factor alone is enough to get me relatively excited about it.
