Referee Deniz Aytekin burst his collar after Bayern's defeat against Leipzig. Thomas Müller even interrupted his interview for the angry speech.
The Franconian had refereed the top match between Bayern and RB, but moved with an action at the center of the criticism of ex-referee Manuel Gräfe. The former top referee observes the performance of the referees as a TV expert for ZDF, and he also repeatedly comments on debatable decisions via Twitter. The situation was also a topic at the Sport1 double pass, where another referee, Felix Brych, was a guest.
