The chance is pretty small for utd to win the game against bayern. Utd will be playing in allianz arena and ten hag's club will have faced kane's squad. I wonder how many goals will be conceded during the match.

Bayern will not even miss an opportunity to get 4 points by playing at home.
Bayern Munich will play with their target to get 3 points from Manchester United and they can do it. They are stronger than Manchester United and even got Harry Kane to improve their attacking power in this summer. The poor performances of some Germany players in latest friendly matches of Germany national team can raise uncertainty in Bayern Munich but even so they are still a stronger team than the opponent.
Personally I think Bayern Munich will dominate and win this match. I have watched every match of Manchester United this season, and I am very bored. Their performance was not satisfactory. Players cannot be confident against big teams. The team lost against Arsenal and Tottenham. It is not possible to beat a team like Bayern Munich with such a performance.
Also, the Bayern Munich team is in a very good rhythm right now. Especially their main striker Harry Kane has adapted well to the team. So Munich's performance accelerated. Of course they will play with the aim of winning against Manchester United. And I think Bayern Munich will play attacking strategy from the beginning of this match.
