Anyone who thinks that there isn't a single player who would try to enginner themselves a move from Spurs should a club come in for them who are the biggest club in England, contesting (and usually winning) the title every year and always in the Champions league needs to get real. The fact that such a move also typically doubles their salary, bonuses, endorsements from their sponsors is another huge carrot that no player will turn down. And all of this is before you consider the fact that the agent will also get a massive pay day.
Remember also that in Berbatov's case this is a Bulgarian guy who'd come to us from Germany and (in his mind) owed us nothing. It hurt when he left because he was a seriously bloody good player, but as soon as Man Utd came sniffing I was always clear that he would be going (just as I was with Carrick).
My thoughts on getting him back now are that it would make perfect sense. We get a player who could play up front on his own, in the withdrawn role behind Adebayor or alongside Soldado. He is a player that has brilliant control, vision, passing ability and finishing skills. He is perfectly suited to a team playing good, attacking football and he would be able to hit the ground running. If he mopes about and is difficult in the dressing room then he doesn't get picked. Personally though I think if we got Berbatov back he would be doing all he could to get himself in the team again and get the fans onside.
