The real question is; how much money would Barca ask for him. IF they dont want to sell him and you have to pay his clause NO ONE can get him. Not in times of FFP and even without that we are talking the world record times 2,5 here.
And he earns more then 20! million euros a year. There are some rich clubs out there; Real, my Bayern and even United with all its debts and wages could go full risk and make such a move. But it would be crazy, you would have to sell big players and the wage structure would explode.
So my question to Spanish football fans. Could we see a move around 130 million max? Then there is a chance.
But 250 million? No way on earth, heaven or hell.
The bidding for him would start at 150M IMO.... having said that I really dont see him leaving Barca for a very long time.
