First, Amauri is not worth 5M. I'm sure we can get 18-22M for both Amauri and Iaquinta.
Second, why would we sell both of our strikers? Sell one, and keep one for depth/substitute.
Lastly, if we sign Dzeko we won't sign Benzema. What are we made of money?
Dzeko, Iaquinta, Quag, Del Piero, Boniperti, Giannati could be our forwards next season.
