Dortmund lost the game to Leipzig but it was not just because of the good performance we saw in Leipzig but I think Dortmund was making many mistakes in this game and to be honest, after all these mistakes they had during this team, Leipzig won the game was not surprising at all. For example, Ramy Bensebaini the defender of Dround scored a weird own goal in this match.
It was quite unfortunate that the two Bundesliga champion has the worst performance ever which is Borussia Dortmund and Bayern Munich, they both lose to a smaller teams they can easily win, actually I don't know if you observed something on today's match because almost all the big teams here and other leagues has a difficulty wining there matches today.
But however of all the matches they have played today, Bayern Munich match was actually what kept me thinking if Bayern Munich deliberately allow Frankfurt to win them or it was there inability to perform well that made them conceive that much.
Dortmund is indeed a big club but Leipzig is not a small club and is not an easy opponent for Dortmund so it is natural that Dortmund suffered a defeat because Dortmund was forced to play with 10 players due to Hummels getting a red card in the 15th minute and this was a good advantage for Leipzig to attack in Dortmund's home ground, this defeat was a very regrettable thing for Dortmund because they could not achieve good results even though in the previous match Dortmund was able to hold Leverkusen to a draw away from home.
Not only you, maybe many people here are surprised by the match between Frankfurt vs Bayern Munich, who would have thought that Bayern Munich conceded 5 goals from a relatively weak team even though we all know that Bayern Munich's defense is very strong and even though this match is very important for Bayern Munich it should be became a victory and could put Bayern Munich at the top of the standings, but unfortunately Bayern Munich did not manage to get full points in that match. Even Harry Kane could not score a goal against the host and this was Bayern Munich first defeat which was a bit embarrassing.
