he has no options basically. higuain is injured, borini is shit, cutrone is not fully match fit, and that's all. i'd be surprised if they managed to snatch a point.
if he was playing as good as he is for Milan, but in the EPL, i believe clubs would line up to pay close to that (doesent mean hes worth that much, EPL morons always overpay). hes still relatively young and a very good player. but serie A clubs cant get those crazy prices for their players somehow (unless they are hyped like SMS or Donnarumma), so i dont think Milan would get 70-80M offers.
