I don't think Leroy Sané will extend his contract with Bayern Munich because it was stated before the end of last season that the club wanted to extend his contract, but it seems like he is not happy at the club. Sané performance was not that bad last season, it is only that he lacks consistency. Bayern Munich has signed another left winger to strengthen their game, they did not get the results they expected last season, and Sané playing time will be reduced next season.
Perhaps Sane is not as good at Bayern as he was at City, but Bayern were going through difficult times and perhaps this is the reason. He plays well and I can’t say that Bayern doesn’t suit him, it’s a good team and I don’t see any reason why he would want to leave. He also had an injury that made some adjustments, but now he is fine and can play at full strength. And he is young enough to think about continuing his career in Saudi Arabia, and I don’t see where else he can aspire, except perhaps to Real Madrid, but I’m not sure that there will be a place for him there now.
