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.
For sure you cannot be certain about the fate of Leverkusen are this point because they are not a week team even if we aren't expecting the same performance as last season from them, they can still be able to get their performance at a good level even if not with thw same record the made last season because obviously they will be treated as a big ream having seen their performance last season, it will only be logical to play more seriously against them because it's believed they have got a very good and strong form on which they can contend top teams.
Their champions league performance may likely be the highlight of their performance for next season because it has always felt like the best point for measuring an European clubs performance are very greatevel.
