Bayern Munich and Leverkusen are both very strong and well performing teams. Due to which the match between them was difficult. If you have seen their match, Leverkusen also managed to score only 1 goal, although they are also a strong team. The reason for this is that Bayern Munich's record is very good and strong, if you look at their close matches, they have only lost 2 times, so I don't think there will be a better record than this because they have a stronger team in their record. Even a match must have passed with defeat. We should also see that Leverkusen is better than Bayern Munich which is why they won this match but it would not have mattered to Bayern Munich but they will definitely want to win this match because they are a strong team.
I wouldn't call Leverkusen better team just because of one game, you do not become better due to just one game, you become better if you are better overall and that's the most important part. I understand that may not feel that great for many people, but that's the most important part. I feel like the best part that could get better result would be something that could get a greater situation based on this game.
Leverkusen has a great way forward with the cup now, not a lot of teams that would be better than Leverkusen left, only team that would be considered better was Bayern and they got that as a win, so whatever team they face, should be teams either same level as them or worse, and that is a great future path for them.
Leverkusen performed well last season. We were all surprised to see such a great performance by Leverkusen. But this season, Leverkusen's overall performance has been inconsistent. Leverkusen has no chance of winning the Bundesliga title anymore. Leverkusen is 7 points behind Bayern Munich and is in third place in the table.
Leverkusen will try their best to win the DFB Pokal title. I think Leverkusen's biggest obstacle in the DFB Pokal title race is Stuttgart. This team is quite strong. Although Stuttgart's performance has been inconsistent. But I think Stuttgart has the ability to beat Leverkusen. I am waiting to see which team Leverkusen is going to face in the quarter finals.
