Manchester City are trying to convince Leroy Sane to sign a new deal before Bayern Munich have chance to launch their next bid for the winger.

Contract negotiations are continuing despite the Germany international being ruled out until at least February with knee ligament damage.

City remain hopeful he will commit his future to the Etihad despite him being widely expected to complete a move to Bayern before suffering his injury last month.

The Premier League champions have always maintained Sane is not for sale, but will demand £137million if he is to leave the club before his current deal ends in 2021.

Bayern did not come up with an offer anywhere near that figure this summer, and it remains unclear whether they will be prepared to meet City’s valuation.

Sources in Germany claim they could be ready to bid as early as January, despite Sane’s recovery from the operation on his anterior cruciate ligament expected to rule him out until February at the earliest.

City have already held extensive talks with the 23-year-old and believed they had reached a breakthrough during the close-season.

Those negotiations then suffered a setback, placing fresh uncertainty over the player's future.

Bayern saw Sane as the perfect replacement for the departed Arjen Robben and Franck Ribery.

But after seeing him suffer injury in the Community Shield, the German champions strengthened their attack with the signings of Ivan Perisic and Philippe Coutinho on loan.
