Jude Bellingham moved to a new city.
The German Football Association is looking into the comments made by Jude Bellingham after the game.
Zwayer was banned for six months for a match-fixing scandal in 2005.
Zwayer gave their rivals a spot-kick after rejecting the appeals for a penalty.
Robert Lewandowski scored the penalty.
Bellingham said that the biggest game in Germany was fixed by a referee. What are you expecting?
The win in der Klassiker gave them a four point lead over their rivals.
It wasn't a penalty for me. ummels is fighting to get the ball and it hits him, he is not even looking at the ball.
You can look at the decisions in the game.
The control committee of the DFB asked Bellingham to comment on his statements as soon as possible.
The control committee will decide what action to take once Bellingham's response has been evaluated.
Michael Zorc, sports director, said that Bellingham is "all but behind" Dortmund.
He was very disappointed and only named known facts, according to Zorc.
Hans-Joachim Watzke said that Jude was not spreading lies, but what happened in the past.
I don't see anything untrue in this statement. I don't think that will have any consequences for Jude.
