For the Bundesliga, right now Bayern Munich is actually going to win it without any doubt this season because the point gap is much for Bayern Leverkusen to catch up with, Leverkusen hasn't been in that sparkling form they were in last season that made them win the league, it would have definitely been a different ball game if they were in same electric form.
Leverkusen's biggest mistake was just letting Munich draw 2x meetings this season. That's why Munich currently looks very convincing to get the title this season. While behind a few more matches and Leverkusen's chances are no longer there to be able to catch up with Munich's points. Maybe the result would be different if in 2x meetings this season at least Leverkusen could beat Munich 1x.
As for the Champions League, I can't really say which team will advance to the next round as in this competition, experience is key and of which Bayern as a team has it.
Experience is one of the opportunities for any team to be able to win the title in UCL. But I still hope Munich does not underestimate Leverkusen in the UCL match later. I am sure that during the previous match, Alonso read Munich's weaknesses which could be a big problem for Munich.
