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.
They should definitely see some of them first team players leaving the club on transfer. The name Jeremy Frimpong has been mentioned notnone not twice as he has been linked with a move to join Manchester United just If Aaron Wan Bisakka leaves the club during the transfer window.
Also, we all saw how porous they was against Atalanta during that finals, I mean the defense, they will be needing some additional players for depth and also upgrades and they will be involved in the Champions League Competition next season. Better depths to with a the test ahead of the new season would be appealing to the management.
About Florian Wirtz, we will see the speculations that will arise during the upcoming Euro's, that will determine if he stays or leaves the club completely and Real Madrid have been top guns chasing him. I will love to see such a top quality midfielder'play with Kylian Mbappe anyways.
