Florian Wirtz is one key frontline for Bayer Leverkusen and Xabi Alonso will not take things likely with his opponents next season. Bayer Leverkusen won the Bundesliga title with unbeaten run, they didn't record a loss and we know they're the best German club this season, surpassing Bayern Munich and Borrusia Dortmund.
Bayer Leverkusen have other plans to meet up, winning the UEFA Champions League title is their target but they should ensure they're having one of the best competitive squad because this is no newbie title but meant for top clubs.
For the Bundesliga title next season, I am still quite confident that Bayer Leverkusen can secure it again and also smaller trophies in Germany. However, for the Champions League, I think there are still stronger candidates for Bayer Leverkusen to face because to win there you not only need strength, but you also need a very good mentality. We can see from Real Madrid who have successfully won their 15th trophy this season where their mentality was really strong in that match even though their opponents were much better in terms of defense and ball control.
