Apart from the Bundesliga, Bayer Leverkusen will return to competing in the Europa League again after the previous season failed to shine in the Europa League. And next season it is hoped that Bayer Leverkusen will shine even more in the Bundesliga and also the Europa League so that their coach's success can be seen even more despite having a lot of experience.
This means that Bayer Leverkusen still has to target several good players in the transfer market from now on so they can better organize next season because Bayer Leverkusen will not be able to get good results more easily next season if they only rely on old players. So Bayer Leverkusen must also be able to move to target several players so that they become stronger next season.
To be honest, I don't have much information about this club. however, it seems that Xabi has the potential to bring Leverkusen to become one of the teams that can become a competitor in the top 4 of the Bundesliga next season. moreover, if he gains support by bringing in some potential newcomers.
As far as I know, only Xhaka wants to be brought in by Leverkusen. although there is no certainty, but the contract has been sealed if Arsenal get a replacement. for other newcomers, I don't really know it. apart from that, if Xabi Alonso continues to carry the playing style of the system that he applies. Xabi needs some ideal new additions, I mean potential players. thus, Leverkusen can compete competitively at the Europa League and Bundesliga levels. at least, Leverkusen has the chance to finish in the top 4 of the standings. but with the condition that I said before, he needs some ammunition to strengthen the depth of his team.
