Considering the result of Barcelona vs Bayern Munich head-to-head match, Bayern Munich team should be ahead in this match. However, in football, the favorite team cannot always be selected by considering the statistics. Both Bayern Munich and Barcelona are very strong teams.
But one important thing is that we have not seen Bayern Munich team play well in the last few matches. Munich share points with Leverkusen and Frankfurt in the Bundesliga. Munich was defeated in an away match against Aston Villa in the Champions League match. So it will be very difficult for Munich to win the away match against Barcelona. Also let's not forget that the coach of Barcelona is now Hansi Flick. Hansi Flick has a good idea of Munich's overall gameplay.
Although in H2H, Munich is far superior, but for me the new coach that Barcelona currently has has intelligence in the strategy that will be used. In my opinion Barcelona is currently missing an injured goalkeeper and this is one of the weaknesses that Munich can exploit. On the one hand in terms of player quality, Bayern Munich has more qualified players and there is no other choice for Hansi Flick except to use a defensive strategy to try to hold the match to a draw.
