I don't doubt Xabi Alonso as long as he is still at Leverkusen, just give him the players he wants, I'm sure next season he will bring Leverkusen again to become champions in the Bundesliga and in European competitions, but we don't need to talk about next season because Xabi Alonso might be better. focusing on the hunt for the title in the UEL and the DFB cup, if they are successful of course they will get the treble winner this season while also declaring themselves an unbeaten team for one season both in the domestic league and in European competitions such as the UEL.
Next season Leverkusen must improve their game because they will play and move up to a higher level, namely the UCL, where this European competition is filled with the best and most experienced teams, this will be a new challenge for Xabi Alonso, if he is still at Leverkusen next season it is certain that Leverkusen will be an even better team than this season, of course the other teams are also no less likely to improve themselves, even the main squad, therefore there are many new things that will come next season, the competition may be very tight both in the domestic league or in the European league.
Rest assured that next season will be more difficult for Bayer than this one, because they will play as champions and each team will play against them accordingly. In addition, no matter how difficult it is for Bayern now, they will want to regain the champion title. I know that not everything is going well for them now, there are problems with finding a new coach, but even in this situation, look at how they played the semi-final with Real Madrid, these were two very worthy matches that they played on equal terms and perhaps many will disagree, but in some Bayern were better than Real in stretches.
Bayern are not going through easy times, but all teams go through this. And Bayer is doing well, has a successful season, and now it seems that it will always be like this, but in reality everything could be different and I don’t know what will happen next season, but I’m sure that Bayern not allow to spend more one such season where Bayer can become champions ahead of schedule.
