It is a winning streak of two games for Dortmund now. After a poor form they started to get positive results. They are only three points behind Bayern Munich at the moment. But I still doubt Dortmund's general effort this season. I think it will be similar to the previous seasons and they will finish far behind Bayern Munich.
It was a very difficult match for Dortmund. However, I am not happy with Dortmund's victory in this match. Because the performance of Frankfurt's players in this match was much better than Dortmund's. A lot of efforts were made by Frankfurt players to score goals and earn points in the match. But as Dortmund tried to keep their defense strong in the match, Frankfurt did not manage to score points in the match despite many attacks. Personally, I am not happy with Dortmund's performance.
Don't forget that one quality of strong teams is to also win when they play a weak game. There are also games when one would say that Bayern deserved a loss, but they often take it home anyway. Dortmund didn't present itself very strong, that's right, but when you get away with some luck at times that can also give you some extra motivation for the next game because you know what you have been doing wrong last time. It could also be the other way around of course.
Now we also shouldn't forget that Frankfurt isn't just any team. They are in great shape right now and a serious competitor when it comes to the top of the table. One scene in the game was stupid though and that was when Frankfurt was denied a penalty. It obviously was a penalty and the referee even apologized after the game. That would have turned things upside down for sure.
