Nothing can stop Leverkusen to win Bundesliga this year and I will keep this bold prediction for the rest of the season. Sure , Bayern looks strong , healthy and always ready to win but Leverkusen looks more like a team than Bayern in my opinion and this will be a huge advantage when they will face each other later.
Also , Stuttgart really wants to catch an European spot for next year and by the way they are playing right now , they can achieve at least a Conference League spot.
The way Leverkusen are playing is really impressive. Today against Dortmund their performance was again really good. There was a dominant game by Leverkusen but they weren't on their good day on one hand. Because despite trying really hard they still couldn't score more than one goal. Even that equalizer came quite late in the game.
I mean Dortmund could have even won here without showing a decent performance. Because I can't say that they were good at all today. But it is normal to see that because of Leverkusen's great system. Especially in away games your job is much more difficult against them.
