This match will be the most anticipated event in the Bundesliga this week, but it may be an overstatement that it will be the decisive one of the season. There are still a lot of matches left until the end and during this time anything can happen, injuries, recessions and anything else that can affect the position of the teams in the table. This match is of course very important, there is no denying it, but even if Bayern loses (which I doubt), they will have a chance to turn things around.
We wouldn't be wrong if we say that the winning team will be relieved. The winning team will have won an important victory. Therefore, I think we would not be wrong if we say that it will be a match that will affect the rest of the season. It's a very important match. Even though the season will continue, the result of this match will have important consequences for the championship.
This is like the clasico of the Bundesliga this season
But in this specific situation in the Bundesliga I strongly agree that this game could have an enormous impact on the outcome of the whole season. Nothing would be won or lost if Bayer Leverkusen loses or ties the game, but if Bayer Leverkusen wins the game, I think it would release such a strong momentum for all the games to come that Bayern might not be able to stop Leverkusen anymore.
The effect would be two-fold. It would push Leverkusen further to keep winning their games while media and the club would go crazy when Bayern loses this game. Tuchel would be stressed again and there would be a lot of turmoil.
