He might if enough money was offered but I doubt anyone will buy him. He's a great player but I still don't see him leaving villa.
If he has any ambition he will, every player should look back at his career once it's over and check out his trophy cabinet and wonder if he did the best he could during his playing days. If you are a great player and have ambition you want to win stuff and play at the top level and Aston Villa just are not there at the moment so you could not blame him for wanting a move to a club playing at a higher level of football. He should want to be seeing European football and if he is good enough the clubs seeing the Champions League year after year should be trying to sign him. Personally I think he has to up his game a bit yet before this becomes the case.
