It is normal for you to make such comments because Leverkusen was defeated in the UEL final, but if they had won, different comments would have been made. Leverkusen had a great season and suffered only 1 defeat in all matches. The Leverkusen coach is not inexperienced. It means he has old experience. He achieved great success in his first season. I hope next season will be better for Xabi, but I don't think it will be better than this one.
Maybe that's true, because maintaining that performance will be more difficult for Xabi to do. On the other hand, other clubs will also be very alert when dealing with Leverkusen, and Atalanta is a club that will be a role model for beating Leverkusen. because Atalanta is the only team that has managed to beat Leverkusen this season.
Even though it won't be as good as this season, I hope they will at least still show something great and be able to provide competition, especially in the Champions League. This will be a place to prove for Xabi Alonso that he is not only great at domestic level, but he can also compete in the biggest competitions in Europe. If he succeeds in bringing something extraordinary again in the Champions League, then he will become a coach that many big clubs will compete for, because in just one season he received many offers, but he prefers to stay with Leverkusen for at least one more season.
