Well that's where we disagree, I see Trezeguet just as important as Nedved, Buffon, DP, Camo, etc. and would only consider selling him if he demands to leave, like Zidane did. Cashing in on a player that stayed in Serie B with this club is downright disgusting IMO.
People quickly forget what he gives on the pitch and I won't get into numbers and statistics because I'm tired of it already. It's always the same story with Trezeguet. In my book he's showed his quality in the last decade and in my eyes is one of the best true poachers ever, the type of attacker which is dying out. He can still bang in goals like no other, including Amauri. I'm not afraid for Trez, he's a determined player and if he recovers from this injury fully, he'll give Amauri a run for his money this season already, you can be sure about that.
My solution is keep all our attackers, who's to say next year Amauri won't be on the sidelines? Or DP? You almost never have all strikers fit, or very rarely.
As for Benzema, I've never hidden my admiration for him, but I was merely making a point about keeping our legends. I don't think we have a chance in hell of getting him, no matter who we sell. And he is above Amauri IMHO.
