Bayern has been planned to get some strong strikers and additional player for its club. The fact that if there will be so many prepration will have done by bayern caused by it will be facing PSG in the last 16. Union berlin was nothing for now.
It seems like that domination from bayern in this season absolute and another team can't replace bayern in any case. Bayern will be winning the trophy again with more than 80% chance.
The very bad performance of Germany in World Cup can affect Bayern Munich too. Germany have many players from Bayern and look at their performances in World Cup, it is not good for Bayern when they meet PSG in Champions League.
The bad ability to score goals in World Cup of Germany have contributions from Bayern players too. Their club will have to seriously filter good strikers in January transfer market and buy one to fill in a position left by Lewandowski, then Mane. Choupo-Moting is not a striker who is reliable enough in big matches. He did not get a position to play in PSG before moving to Bayern.
