There may not be easy matches like last year in the German league because most of the teams transferred a lot of players. The league became more difficult with the transferred players. For example, Borussia Dortmund's offensive line got much stronger. Bayern Munich also got stronger with good players. Kompany also made tactical changes. Bayer Leverkusen's squad from last year may be successful this year, but it may not be.
I also think the same, that Leverkusen will have a hard time next season even though they themselves also had a not so good pre-season, and I think Xabi will find it difficult to evaluate all of this because the players he received there are not superstar players so it is difficult for him, and I think Leverkusen will have a hard time getting into the top four next season, how could it not be Stuttgart Dordmund Munich and also Leipzigh have abilities above them at the moment and they also have good transfers so I think Leverkusen will not endanger the Bundesliga next season.
But I am very sure Stuttgart will make something to be proud of how could they not have a good transfer and they still have a pretty solid coach on the sidelines and I think they will surprise many Bundesliga teams next season with the good strength they get and Leverkusen will experience that dimness in my opinion because Leverkusen did not make the most of this transfer by adding good players so a setback will happen to Xabi.
