The worry would be how much money he wants. I wouldn't have thought he'd be an immediate first choice. We don't want £40k p/w players sitting on the bench most weeks. Those days are behind us.
Distance between the defence and the strikers is too large which is resulting in long ball. Was much better when we were 4-2-3-1 with Cabaye at the top of the midfield :/
He'd be a very atypical Barcelona player, like. Really direct. Only way I could see him fitting in would be at left back and I think maybe you'd have to play a more defensive right back to accommodate that as well
