It could still be that the absence of Lewandowsky has a major impact on this Bayern Munich team. After all, Mane is a completely different player and a completely different caliber than Lewandowsky. Too bad he didn't win the golden ball. Union Berlin - Bayern Munich has already been played in September and that has become 1-1. They will play against each other again in Munich in February. Perhaps an important game, but it could well be (and what do I expect) that Bayern Munich will already have a big lead. I can't imagine Union Berlin being able to keep up this pace like this.
Lewandowski has a big impact on Bayern Munichs team because he scored 40+ goals per season and they just didnt get a similar striker. They got Mane that is a winger and putted him in a striker position so that changes a lot of things. They are still really good but not that deadly.
We should not talk about Lewandowski anymore, because it wasn't the club that decided Lewandowski's contract but Lewandowski himself who wanted to leave Bayern and he wanted to move to Barcelona, I also don't like it when they compare Mane with Lewandowski, Mane still needs time to adapt with Bayern players, give Mane a chance and let Mane enjoy his game at Bayern no longer compared to Lewandowski.
Bayern Munich's management tried their best to keep Lewandowski in the team. But Lewandowski was not interested in staying with the Munich squad. And he voluntarily left the Munich team. So we should not think now that Lewandowski was good for Bayern Munich. But I would say Sadio Mane should not be thought of as Lewandowski's replacement. Mane and Lewandowski have completely different styles of play. Lewandowski is a regular scorer and Sadio Mane is a playmaker.
