As much as I agree that this is the time to sell Bonucci he's going nowhere. He'll stay and become a bandiera for this club.
Rugani will be brought back and yes, Ogbonna should worry about his position. Anyway I don't think they'll shop him away. If there's a good offer he leaves. Otherwise they won't try to sell him at any cost.
Rugani will struggle to find playing time if Barzagli is healthy.
