How many Juve players were sold for above 39 mil, account for inflation adjustment. Vidal is not young and his play style requires peak stamina. He stays free of injury for couple months can not justify for his price tag YET, for 39 mil you will expect a player be vital for a team at least 2 - 3 season. Wait and see after 3 seasons and then we can conclude. Similar thing can be said about Coman's transfer.
