Absolutely true and that is an achievement that is rarely achieved by other coaches on their first debut with their new club. Xabi Alonso has gone so far from most coaches and who would have thought that he would achieve such impressive results at a mediocre club that doesn't even have star players. It could be said that this kind of success only comes once in a lifetime and Xabi Alonso has found the right formula for Leverkusen's revival.
Defeat is as normal as winning in football and this defeat will definitely make Leverkusen more mature and can make them strengthen what they already have. Talking about the DFB Pokal, Leverkusen certainly doesn't want the same mistakes to be repeated and even though their opponents will be a weak team from a lower division, they can't underestimate them in the slightest if they want to win this title.
Although many are trying to judge Xabi Alonso after losing the Europa League final to Atalanta, we should understand that nothing lasts forever, so any club can get defeated by any opponent. Although Bayer Leverkusen has beaten top clubs that are stronger than Atalanta this season, like Bayern Munich and others, they played 51 games unbeaten in all competitions. So I don't think we should be surprised that they got defeated by Atalanta who lost their many games this season. This team has come far from the start of the season, and it looks very difficult for any team in the world to maintain their winning ways throughout the seasons. Xabi has broken Benfica's 48 games unbeaten, I believe that it will be rare for Bayern Munich to achieve this in the Bundesliga league.
However, I believe that Leverkusen will not make this mistake again because this is their last game of the season and the second trophy. Bayer Leverkusen will face no challenges playing against Kaiserslautern because they performance isn't good in their league, they are currently at the 13 positions, and I'm not sure how they qualified for the DFB Pokal Final.
I actually think that Leverkusen might have actually felt a little too much invincible. They had to get humbled. And in the Europa League final they got humbled. They had achieved a lot in this season. If they were actually able to win both the finals that were left, the Europa League final and the DFB pokal this could have been the perfect season. But that did not happen. I thought they would probably be able to finish the season without a single loss in all competitions. But they ended up losing a crucial match. But anyway I think what they have achieved so far is really good and not every club can say that they have achieved similar kinds of things. Taking the trophy away from a club that has been the champions for 11 years is definitely not an easy job. They have done that. The Europa League might not have ended as we expected but I think the DFB pokal is actually going to finish in favor of Leverkusen.
