If we do get Chevanton it wont be based on Trez leavinng or not, because if Trez leaves we will still buy another striker Im quite sure.
But the best thing would be to sell Di viao and bring in Gilardino and keep Trez, That would leave us with Del piero, Miccoli, Trez and Gilardino, Two small and two big ones, (even if Gilardino isnt a giant may I add)
