I see Dortmund as a fairly big team from the Bundesliga did not show a good performance. Indeed, they got a win from their opponent, but actually, conceding 3 goals is not good for Dortmund. Fans' expectations of Dortmund for the group phase should not be a problem in qualifying. But overall, the game still has many shortcomings. Fortunately, the second match did not end in a draw or loss, otherwise many fans would be pessimistic about a bad new season.
A standard story for Dortmund - after a series of bad games there is a series of good ones and vice versa, many at the moment think that finally serious changes have occurred, but no. Last season, Dortmund showed phenomenal results after the change of coach and they were able to rise from the depths to the Champions League zone, but now I see all the same signs of instability. Sometimes I think that if you correctly guess when Dortmund starts a bad streak (or vice versa, a win streak), then betting on them you can become a millionaire
But at the start of next season I will just wait first and if there are no signs of obvious progress I will throw them out of my cash bets for the season, last season I burned a lot of multi-bets because of them.
Maybe the old Dortmund story will still happen in the new season, but at least they are still there for us to try to place a bet. I have left United out of my bet. If Dortmund are bad at the start of the new season, I think I have to exclude Dortmund from my bet too.
Hopefully, they will be better in the new season, if they prepare well to strengthen their squad. Dortmund can definitely perform better.
