Düsseldorf is a great team who is currently in the top three, I am not sure Bochum will win this match because the opponent they face is quite strong and difficult to beat. but we know that when in the field anything can happen. Here there is still a possibility that Düsseldorf will give Bochum a chance to win and survive the relegation zone.
Bochum has lost by three goals without reply at home in the Qualification Play-offs match in the last three days and I am not sure that Bochum can make a big comeback when competing at home to Fortuna Düsseldorf because the Bochum team will have to score more goals to stay in Bundesliga next season. So the second leg match for the Qualification Play-offs seems to be a bit difficult for the Bochum team to win because Bochum is already behind with more goals first.
Bochum had lost by 3 goals in the first leg which was played at their own home so there was no longer any possibility for them to turn things around in the second leg when they played at Fortuna Düsseldorf.
Looking at it as a whole, this season, Fortuna Düsseldorf is much stronger than Bochum, especially since their motivation is only one step away from being promoted to the Bundesliga, so I think this is only natural.
