According to the press this week it's Barca
He doesn't fit in with Barca's style of play though IMO. He's too direct for a deep-lying midfielder and I don't think he's actually good enough in the head to play in the Barca team. They are full of very intelligent players, and whilst he may be very quick and have an excellent shot and passing range, I just don't see him fitting in at all.
Also, I can't see them wanting/needing him. Where would he fit in? Because Lordy knows he ain't dropping Xavi/Iniesta, so it looks like a place on the bench for a fella pushing 30 costing £130,000+-a-week. Makes no sense.
