Based on Bayern Leverkusen's success last season, I am certain that they will do well in the Champions League and possibly reach the final. Because of how well they performed in the Bundesliga last season without losing a match, and if Atalanta has luck and breaks their unbeaten streak in the Europa League, and Xavi Alonso is still the coach next season, they will most likely perform well and challenge the big clubs in the Champions League next season as well, because I enjoy how they perform and play on the pitch.
Let's see if they can win the Champions League next season although it won't be simple. If Manchester City and Madrid are already eliminated, we can guess that Leverkusen will win the trophy. Because I did not see any performance, I believe Barcelona will face PSG in the Champions League next season because they are not prepared to win the title. PSG no longer has any major players in their squad the only one is Mbappe, who has left for Real Madrid. Can they add a significant player like Mbappe next season and compete in the Champions League, Barcelona may not win any titles if they do not get crucial players to the team.
