Kucka will remain this summer, but they've already lined up his next club - and it is thought to be AC Milan.
"Kucka will stay here and he'll play for us next season," Rossoblu chief Enrico Preziosi stated. "That will still be the case even if I received an offer of 30m.
"There are three clubs after him, but we have already identified one outfit with which we'll talk to about the player's future.
"There are talks already open with a club whom we have had several transfer dealings with in the past."
