I overestimate Bayern Munich's current success because in the Bundesliga they don't have much pressure and also Bayern Munich is very consistent so there is no significant pressure from other teams and that is inseparable from the team plan that was built better this season after slumping last season.
And for Bayern Munich's victory in the last 16 of the Champion League from Leverkusen is also not a big surprise and I even still think that Bayern Munich has not shown good performance in the Champion League competition.
Maybe now Bayern Munich should focus more on being able to go far and win the UCL trophy because for the Bundesliga they are almost certain to get it.
I also think you were wrong to overestimate Bayern, unfortunately it happens in football.
It was probably a particularly unlucky match and this also happens in football, sometimes even if the team you face is weaker than you you end up losing, this also happens in football.
