Bayer can now focus entirely on the Bundesliga, they don't have any prerequisites yet to hope that they can defend their champions title, but they have to try to do it, and for that they need to win all the matches, they can't lose points, so even though Bochum is not the easiest team, I expect Bayer to beat such an opponent. On the other hand, I doubt that Bayern will lose the difference that they were able to make.
Bayer Leverkusen is the team that will definitely win the match against Bochum. We all know the difficult conditions of the Bundesliga. Xabi Alonso in Leverkusen wanted to repeat last year's success but they are not in a similar ranking this year. Still, they continue to chase Bayern Munich for the championship. They will need to win this match to continue this until the end of the year. I see Leverkusen as the favorite in this match because they will be playing on their home field.
Yes, of course Bayer Leverkusen will definitely win the match later because Bochum is not an equal opponent in the Bundesliga. The competition is getting tighter, the top three teams are chasing full points, this year's Bundesliga is a little different from last year, every time Leverkusen plays they will get 3 points or a draw.
I also hope Leverkusen can defend their title like last season even though it is not easy, Xabi Alonso will continue to show his best game in order to win all the remaining matches, the point is the match between Bayer Leverkusen vs Bochum will be won by Leverkusen, especially since they are playing at home.
