He's going to justify his 45 million euros ($52 million) transfer from Manchester City.
Sane is set to start away to Benfica in Lisbon with visitors Bayern chasing a third straight Champions League victory to stay top of Group E after wins last month over Barcelona and Dynamo Kiev.
Neither club managed to score past Bayern, who have scored eight goals without reply so far in Europe, and Sane deserves some of the credit after improving his pressing in the opposition's half.
As Bayern head coach Julian Nagelsmann points out, Sane has been "throwing himself into the defensive work full force. He has made incredible steps in counter-pressing".
It's not always been the case.
Sane joined Bayern from City in 2020, but struggled to make an impact last season as questions lingered over his defending.
