Bayer Leverkusen treble accomplishment shattered and they have to settle for two titles this season. The DFB-Pokal was important for Bayer Leverkussen after failing to win Atalanta in the Europa League final. They've been one the promising club this season with just a defeat. Xabi Alonso is currently the main instrument, he has helped his club deliver good news and will always do the pushing moves to making things running smoothly.
The best effort is always important for a club like Leverkusen and Xabi Alonso has also proven that this season and must be able to continue to bring that kind of effort next season because next season Leverkusen will be in the UCL which is a much greater competition than the UEL So it is hoped that Xabi Alonso will be able to do much better next season in order to be able to compete with teams that are more elite than the ones they faced this season in the UEL and Bundesliga.
Even though next season Xabi Alonso will still be at Bayer Leverkusen, but I am curious whether there will be big changes in their squad or not. Because after all, it seems like there are a lot of rumors circulating about Florian Wirtz who is interested in big teams out there like Real Madrid. Even though maybe it's just a rumor, but I think it's very possible for them to leave, especially about the offer from Real Madrid is always tempting. But yes, whether there will be big changes or not of the Bayer Leverkusen squad next season, at least Xabi Alonso will still do his best of course to make Bayer Leverkusen remain great next season because of its status as defending champion.
I still respect Xabi Alonso no matter that they were unable to win Europa league because of his coaching skills which has made him to achieve a record that no coach have achieved throughout the history of Bundesliga. If it happens that Writz is leaving and some other players, he will get a replacement and he knows the player that he will be bringing over that he can do the job.
We might still see a new name from this present Leverkusen squad that will take over the scoring as we have seen that in the past with several clubs. I don't think that it will be a problem for Alonso if he loose some of his players that are after big clubs, he will still build up the team to be as strong as this. However, it will be much better and a relieve to him, if none of his men leaves.
