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 to play these matches because of the goal difference. Union Berlin might have had to play these games instead. It looks like a tragic farewell to the Bundesliga. They had a very bad result in the first match. They conceded 3 goals and didn't score any. For me it would be a miracle if they score 4 goals in this match. There are such miracles in football. But Fortuna Düsseldorf showed in the first match that they are a better team than Bochum. I have no clear idea about the outcome of this match. I won't bet on it, but I think Fortuna Düsseldorf is in the Bundesliga.
