Why though? If a player is available and will improve the squad then why let silly grievances get in the way? He didn't publicly slate us, he just got a better offer at the time. If an offer from Real Madrid had been on the table when we signed Kompany, Zabaleta etc then they probably would have rejected us too. All of our players are with us because at that particular point in time, they felt that City could best serve their careers and/or bank balances. They arrive for professional reasons, but so long as they as do their best and hopefully come to love the club over time then i don't see the problem with that. There's no reason why Isco couldn't do the same.
