After watching the defeat of Bayern Munich, we saw the defeat of another Bundesliga giant, Dortmund. Dortmund lost 3-2 against Leipzig. The Dortmund team failed to win the home match as well.
One of the reasons for Dortmund's defeat was Mats Hummels' red card. Hummels left the field after receiving a red card just 15 minutes into the match. It is very difficult to perform well with 10 players against a big team like Leipzig and Dortmund conceded the first goal of the match in the 32nd minute due to a mistake by defender Bensebaini. And even then it became more and more difficult for Dortmund to win this match. In the end the match ended 3-2.
Dortmund's performance has declined in their last 5 matches, but if Dortmund didn't lose 1 player in this match due to a red card then I think the result would be different. Dortmund could still score 2 goals even though they played with 10 players, but they couldn't do much because Leipzig were too good to beat.
Basically Leipzig is not very stable either, but they are still better than Dortmund this season. Of course not only in the Bundesliga, but Leipzig also performed well in the Champions League by securing a ticket to the round of 16. But considering that the competition is still long, there is no certainty whether a team and their position in the standings will change.
