Bochum is a mediocre team that cannot be compared to Bayern Munich, and even though Bochum can beat Bayern Munich, I'm sure this won't happen again. What's more, Bayern Munich's position at this moment is indeed required to win, so playing against Bochum is a big chance for Bayern Munich to be able to win and even with a big score.
Also, regarding the match between Leipzig v Union Berlin, I think it is not certain which team will win this match because they have good quality at this moment. But because Leipzig is playing at home, Leipzig should be able to take advantage of playing at home to win.
Bochum can surely surprise us sometimes, but I think Julian Nagelsmann can sometimes surprise us aswell, and readying something now that Sadio Mane can not play, they really didn't see this coming, and only 1 player is absent, and Bayern Munich was outperforming by being other teams, that 4 consecutive draws that they got from Leipzig, Koln, Frankfurt and also Salzburg but right now I think Nagelsmann really did it and right now latest 2 games of Bayern Munich is likely getting back their winning strategy, against Mainz they got 0 - 4 and Wolfsburg that is getting their performance increase, Bayern Munich won 2 - 4 against them, while I think with this new-found strategy of Nagelsmann for me they will surely win against Bochum, they really need to win this because Union Berlin is just 1 point behind them,
And speaking of Leipzig VS Union Berlin I still don't know who's going to win here, but at some point if Union Berlin won against Leipzig then I will admit that they surely a change team, but if Leipzig did win this Union Berling is just lucky,
Leipzig are lacking one of their most important players now, Nkunku. He is the most scorer for the team with 12 goals now and he is the second in top scorers as well. Of course Leipzig still have effective attackers but we will see what they will do this time. Union Berlin is a really serious challenge for them indeed. Having a home match can be seen as an advantage for Leipzig but they won't be comfortable in this match. Union Berlin beat them here by 2-1 last season so Leipzig should take this match very seriously.
Bayern Munich had better take advantage of the opportunity to open the gap with at least one of those teams meanwhile.
Leipzig should not fail in winning this because they are 1 point behind Dortmund and they need to catch up against Union Berlin as well, right now even without Nkunku, they can not rely wholly on Christopher Nkunku, and use their remaining players just like Bayern Munich are doing right now they are using available players because Sadio Mane is not around,
