If we get a Big offer for Torres I would get rid, not because I don't like him as a player, but I think the money he would bring in could be used to bring us in a number of quality players which would be bigger benefit to the team than he can be alone. If he gets injured again we are screwed, 3 or 4 decent signings in his place is less risk.
If you were going to sell Torres, you would have to get the decent players in first. He is one of the main reasons why quality players would come to the club in the first place so if you sold him first you would struggle to attract them!
He has worldwide appeal and players want to play in the same team as him.
Personally, i wouldn't sell Torres for any amount. I just want to see him supported by better players and then watch the goals fly in!
