'The referee was wearing a Bayern jersey!' - Mainz star aims incredible accusation at official after first-half demolition against Harry Kane & Co

Four first-half goals from Bayern, including a Jamal Musiala hat-trick, were enough to put Mainz to the sword and send the visitors through to the third round of the DFB-Pokal. However, plenty of the home team's players were left furious at the officiating in the match and Kohr has gone so far as to accuse the referee of having a Bayern shirt on in a blockbuster interview.

Speaking after the game, Kohr said to Sky Sport: "The referee had a Bayern shirt on today. We have to say that clearly. Every little call was in Bayern’s favor. The second goal was a clear offside. That’s the Bayern bonus."

Even if the referee got a few decisions wrong in the game, Bayern were dominant throughout and good value for their win. Vincent Kompany's men boasted 80 per cent possession in the match, along with 15 shots over the course of the game.

It would not be surprising to see the defender slapped with a punishment of some sort for his outburst. Usually players are fined for such comments but there have been instances where bans have been handed out for extreme cases.
