I'd rather Bayern Leverkusen on my list than Bayern Munich.
Leverkusen are on a great run with Xabi Alonso. They can't be underestimated in the Champions League at all. However there is still a huge experience and success gap between Leverkusen and Bayern Munich.

Bayern Munich have a great history with 6 titles here. Leverkusen have only 1 runner-up season and that's all. They have a great momentum recently but experience plays a really important role in the Champions League. I don't think they Leverkusen will do better than them honestly but it is just my opinion.

Also, another team I'd rather is Barcelona. Most importantly, it'll take some time and patience but they'll definitely be one of the best clubs in La Liga Competition again and this I'm certain.
Hansi Flick is a top quality coach at a top level, what's remaining for him would be qualified and quality players who can play the La Ma Sia system.
Barcelona will need time and new transfers to bring back their strong days. Hansi Flick is a great manager choice but the squad should be more competitive where Real Madrid is signing Mbappe.
