If we really really had to sell someone its either Iaquinta or Amauri.
If we sell iaquinta: is because of his chronic injury problems.
If we sell Amauri: is because he wasn't capable of recovering his goal scoring ability.
That is said, it is too early to judge Amauri. The whole team has been playing so poor and he was up infront alone. If we continue to feature Del Piero or giovinco next to him he will eventually come out of the cave.
