The two teams that qualified for the finals of the European League this season will play in the Champions League next season, which means that the competition for the other teams has become somewhat easier. Leverkusen only lost one match and because of this one miss they failed to win the Europa League title. But I will definitely appreciate their performance as their performance in last season's local league tournament and Europa League tournament was more than expected. I will definitely expect them to do well in the next season, especially in the Champions League, if they make history.
In the Champions League his performance will be different even though last season Leverkusen made an extraordinary breakthrough so that more people were amazed by him. However, in the Champions League, Leverkusen will meet more great teams, including Atalanta, who beat them in the Europa League final last season. So the level of performance from Leverkusen itself will definitely be very different from the previous season and even if it can be the same, I think it will only happen in the Bundesliga.
Maybe, if in the group phase Bayer Leverkusen is not together with the top teams, then maybe Bayer Leverkusen will have a chance to become group winners or maybe just runners up. But the point is, I personally believe Bayer Leverkusen is capable of advancing to the knockout phase of the last 16, the quarter-finals or maybe even qualifying for the semifinals. Because I personally am still quite confident about the quality and abilities of Xabi Alonso, even though there may be several key players who might leave, but I still believe Xabi Alonso will be able to make the Bayer Leverkusen squad good next season. Therefore, failure to win the Europa League trophy and at the same time failing to win the treble winner last season will of course allow Bayer Leverkusen to improve better next season.
