FC Bayern President Herbert Hainer recently gave an interview to the German
Kicker. He said that its likely that Manuel Neuer, David Alaba and Thiago will stay Bayern. IMHO this statement makes contract extensions much more likely. Why would he say something like that, if the players are about to leave to another club?
Hainer on Alaba, Neuer, Thiago: "We assume they will stay. Why should they leave? They play for one of the best teams in the world, at one of - if not the best - run clubs in the world. They live in an attractive city and we pay them top wages"

Concerning the transfer of Leroy Sané, Hainer announced that Bayern will only a price that is economically acceptable.

Signing him for free like they do with RL9? Yes, sir but I don't see a scenario in which they will break bank for him.
