As long as Bayern still cannot be stopped by any club in the Bundesliga, in the end the opportunity to approach will be very difficult because in the end we can see that for now Bayern can still continue to take advantage of the opportunities they have so that their points are still maintained until now because whether we realize it or not, Bayern is currently showing a very good performance, different from what happened in the 2 seasons that have occurred in the Tuchel era which always had difficulty in taking advantage of momentum.
Right now what Leverkusen has to do is just try to stay consistent while hoping that Bayern can't get points, but in the end this is also difficult, even for Frankfurt, which is currently a dark horse, they still can't hold back Bayern's dominance, so as long as Bayern can't be held back, I think they will still be champions for this season even though the game still has about 15 weeks left.
I actually don't like how Bayern is playing these days and they have some very bad performances, but as has been mentioned here before, there is no real competitor. I think this Bayern team sometimes is the worst that Bayern had a in a long time, but Kompany is getting away with it exactly because the Bundesliga is quite weak.
I think it becomes quite evident in the Champions League and Bayern should have never had results so close against Celtic. What are they going to do against much stronger opponents? They either grow with the challenge or they will get destroyed for sure.
For German fans it is of course bad news that German teams play against each other so early now, which means one German team will be out 100%. But Leverkusen has a fair chance I think. Dortmund got pretty lucky I think if you compare their match with all those others. Atletico against Real is a big one, PSG against Liverpool is going to be interesting although I think that Liverpool will dominate the game at least when they play at home. I am curious how good PSG will be, but Liverpool in my opinion is a different level than PSG. Maybe if PSG has one of their prime days, Liverpool might get into trouble.
