Bayer Leverkusen have bigger shoes to wear this time around because now their focus is actively divided although last season it was also but this time around it will be the champions league of which they might not be able to Stand most of the top teams there and when you are playing and then you constantly lose games then the form and mentality of the team also deteriorate to a very big extent.
There's nothing different, they were have Europa League in the last season, so it's only change from Europa League to Champions League. The opponents are stronger, but the schedule is same. Looking at their performance, I really doubt they can able to make it to round of 16.
They aren't as strong as in the last season, similar to Napoli.
This year, most of the favorite teams started the league badly. In almost every league, teams that were very successful the previous season are currently in the middle of their leagues. Leverkusen is one of these teams. The team will get better in the coming weeks. If something is not going well, it can be good to take a break, and we are in that break right now. That's why I think the teams that have not been able to show high performance so far will be better from now on
