It won't be that difficult for Xabi Alonso to improve the depth of his squad again next season because Xabi Alonso only needs to polish several areas in certain lines so that his squad can have better strength next season, such as in the defense area and also the attack area. If Xabi Alonso is able to bring Leverkusen to win the Bundesliga without time, of course it is not impossible for him to repeat this next season as long as the players are still quite united and can still carry out Xabi Alonso's instructions.
That's true, Xabi Alonso doesn't have a big problem with his upbringing, he just has to improve a little in the defensive line. with their final match yesterday, in my opinion their defense which was managed to mess up by the opposing team is a problem and must be improved so that they can perform well and be better and I think Bayern Leverkusen still has a chance to dominate again, because their good performance will definitely be maintained and their good performance will even be further honed to be able to become a team that dominates again, including in the Bundesliga.
I think Bayern Leverkusen is ready to compete again with its good performance, although there is a possibility that next season there will be a team that can match them at the start of the season and that might be a surprise, because no one rules out the possibility that they can be beaten However, with the arrival of Xabi, Leverkusen has become a team that has very good performance and I hope that Xabi can continue to do his best to maintain and develop their performance.
