I believe Bayern Munich will win the match by more than two goals because the chances are quite open, even though they are in a bad form after being defeated by Barcelona in the Champions.
Top of the table, RB Leipzig will surely put immense pressure on Bayern Munich to secure a win by a very big margin when they face Bochum. With both teams' points nearly equal, the Bavarians will need more than just three points to keep their goal difference. Bochum, in the first place, is not a worthy opponent for Bayern hence more so in its current state what are the chances that FC Bayern wins with two or more goals? Very open.
After losing to Barcelona in the Champions League, Bayern has just suffered a defeat, and this means that they are very motivated to restore their game back. This match will be another means through which they can restore their confidence. This time they will have to keep fighting at the very top of the competition. If they let themselves grab this opportunity, Bayern will cement its place within the league while proving that no matter their struggles in Europe, they remain a force in Germany.
