Christian Heidl has said a lot that they want it resolved ASAP.
During the Euro's he said he wanted Sané to decide his future quickly, and a few days ago he said that they hadn't recieved an offer yet, but if they did it would be resolved quickly.
Unlike Wolfsburg, who wanted to offer him a new deal or convince him to stay a year, I don't think they're expecting to keep the player, and would prefer to sell for €50m now than €33m next summer. Seemingly it's just a case of us meeting their valuation.
