Franck Ribery plays a prank on the referee during Bayern Munich's match

During Bayern Munich's match against Chemnitzer in the German Cup, Franck Ribery played a prank on the referee.

When Bibiana Steinhaus, who is the first woman to officiate a professional men's match, awarded a free kick to the Bavarians, the French footballer took the opportunity to untie her shoelaces while she was positioning the ball.

After this prank, Steinhaus playfully tapped Ribery's shoulder twice and at the end, both the female referee and the Bayern player laughed about the incident.

At the end of the match, Ribery simply commented, "It was very funny. She had a good performance. You can joke with referees, but mutual respect is important."
