Dortmund have had some significant decline in their results for a couple of weeks in the Bundesliga. It is normal to see such time periods for big teams of course. But the key point is to put an end to that bad streak at once. Dortmund have a home game against Gladbach next time. I think this could be the opportunity for them to do this.
First of all they have been really dominant in home games against Gladbach in the recent years. We have watched many games ending up with very comfortable victories. I don't know if we would see such result but I expect Dorttmund to win here to put an end to this.
I believe Dortmund are having an affection from last season failure, the way they failed hits their mental significantly like what Liverpool experience the season before. Dortmund's mental fragility was evident in their recent match against Bayern Munich, where they lost 3-2 despite taking an early lead. The team looked nervous and indecisive throughout the match, and they were easily rattled by Bayern's pressure. This is a worrying trend for Dortmund, as they need to be able to handle pressure and adversity. They need to find a way to shake off the negativity from last season and focus on the present.
It's important for them to win the game that they expected to win, otherwise they will keep losing confidence in competing again for the title as they used to do it. The game against Gladbach is a big test for them. Gladbach is a tough team to beat. both teams have similar head to head record.
