Compliant or not? Marcus Ingvartsen's penalty in FSV Mainz 05's 5-0 win over 1. FC Köln on Friday evening in the Bundesliga caused some discussion. When he shot, it seemed that the Dane had touched the ball very lightly with his right foot. However, the video referee did not intervene.

"The assumption is quite justified. We also put a magnifying glass on it. We looked at it 100 times in Cologne. Our colleagues did it very meticulously, but could not prove beyond a doubt that it was the case," said DFB project manager Jochen Drees at the Internet broadcaster DAZN: "We can only correct it if there is clear evidence of it."
