still, the player would ask for the same net salary in case juve wanted a sale. no one will play 3,5m to kurzawa if he flops here. an other potentially unsellable, injury prone player.
at least mds is cheap. i'd keep him until the end of the season, and if psg still want him, then sell him before the current financial year ends. same financial effect, without the deadweight kurzawa probably is.
