Sane transfer had looked close to completion, with Kicker reporting last week that terms had been agreed on a Sh11.6 billion (100-million-euro) deal.
Bayern are on the look-out for wingers following the departures of arjen robben and Franck ribery, but club president Uli Hoeness has already admitted a deal for
Sane is unlikely because of the amount of money it will take to prise him from City.

Sane had come on as an 83rd-minute substitute during Germany's goalless draw with World Cup champions France in the Nations League opener on Thursday evening.
