For Bayern Munich, the Champions League is more important than the Bundesliga. So before the Champions League match, it was more important to prepare for the Champions League than to win the Bundesliga match.
Even if Bayern Munich has won the Bundesliga several times because of their aim to win the Champions League, they would not lose their interest in winning the Bundesliga.
As Bayern aims to win the Champions League, they will still strive to win the Bundesliga too because winning the Champions League can’t be predicted. A team can put all their energy into the Champions League, but there is no guarantee that they will end up winning.
I don't see Munich just thinking about the UCL this season because a team as big as Munich should be able to win as many titles as possible each season, especially the Bundesliga trophy which is Germany's main league. So two draws from the 5 matches Munich has played so far doesn't mean they're only focused on the UCL, but rather because sometimes at the beginning of the season, big teams always experience a dip in performance, and that dip usually becomes a point of evaluation to become stronger and more consistent. Especially if we say they're focusing on the UCL even Munich in the next UCL match will face a relatively easy opponent Viking.
On the other hand, I’m sure Munich will still be able to dominate the Bundesliga even though they got a draw, but their rival Dortmund also drew against Bremen. So it can be said that Munich can easily overtake Dortmund who are only two points ahead of Munich. Freiburg is indeed at the top at the moment, but for me, they’re not serious competitors for Munich and Dortmund. Maybe in a week or two they’ll drop points because they have to face Leverkusen and Munich.
