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.
So far it seems that Bayern Munich is doing better without Lewandowski than he is doing without Bayern at the moment. Of course the personal stats of Lewandowski are great at Barca too and he already scored a lot of goals there but in the end Barca will miss the knockout stage of Champions League again this year with 99,9% certainty which is a huge disappointment.
Bayern on the other hand has played a great group stage so far and is already qualified and in the Bundesliga they also seem to be on track again. It is kinda weird. Two weeks ago after the 2-2 vs. Dortmund everyone acted like Bayern is in a big crisis and Dortmund is on a great run. Now 1 week later Bayern is fine again and Dortmund has a huge crisis.
