Bayer Leverkusen lost against Atalanta is one important thing for them as a team, especially for Xabi Alonso as a manager. I believe this could give Bayer Leverkusen a lesson, we know that there is no perfection in any team. So, maybe from this loss Bayer Leverkusen will learn a lot, and ready to give their all abilities for the next season, this is what i am talking about before, so we need to see surprise from Leverkusen and this will be a big surprise for everyone.
Bayer Leverkusen will struggle to make things standing next season because every oppositions they face will likely play their best against Leverkusen. Remember Bayer Leverkusen have one of the current best manager in the European world of football, Xabi Alonso the man that won the Bundesliga title unbeaten and have also dwell more of his valuable time on the squad for the purpose of preparation next season.
