When Agnelli mentioned that we have the oldest squad in Europe and we'll have to replace some older players, it was clear that he was talking about Matuidi, Higuain and Khedira.
Matuidi was the easiest to get rid of. We didn't expect a transfer fee and there was good probability that someone will pay his wages, since Matuidi has experience, stamina and is almost always available.
Higuain is tougher. We will demand 15-20 million in transfer fees and he will demand a high wage. Khedira is almost impossible. We won't ask for transfer fees, but he's old and always injured, plus on high wages. Who on earth would want that?
