If this happens it will be the same as Dortmund last season because in the end they had to give up the champions who were so close. Alonso needs to be aware of this condition because if his players are not rotated he is worried that they will experience fatigue.
I hope Leverkusen doesn't really fail like Dortmund last season where they should have been able to win the title but ultimately failed because Munich has won the title and is dominating the Bundesliga again, Xabi Alonso must be able to keep every player in good condition and not injured, that is his job which is difficult for him to maintain consistency until the end of the season.
But I believe that if Xabi Alonso succeeds in bringing Leverkusen to win the Bundesliga title this season, of course he can bring Leverkusen to get a UCL ticket next season. That will also be the latest challenge for Xabi Alonso to bring Leverkusen to appear in even bigger matches in the European league. like the UCL because it is important for Leverkusen's progress to play at a better level other than the Bundesliga. they deserve it.
Leverkusen has a big chance of getting a ticket to appear in the Champions League next season, I am very sure they can get it from the Bundesliga because it is enough to finish in the top four of the standings. One more ticket can be won from the European League competition, but with the condition that Xabi Alonso must be able to bring Laverkusen to become champions. Talking about maintaining consistency and the challenges that Xabi will face in the future, I think this is very conditional, in the sense that ups and downs in a team performance will definitely happen. As a manager, Xabi really understands the level of competition and challenges he will face in the future, and we have seen his performance with Laverkusen in the first half of the season, Xabi was able to do very well.
