Jude Bellingham has launched an extraordinary attack on referee Felix Zwayer, bringing up his involvement in a past match-fixing scandal, following Borussia Dortmund's 3-2 defeat to Bayern Munich.
Dortmund players were furious with the referee over a number of decisions during the derby match, in particular a penalty which was awarded after Mats Hummels appeared to handle in the area when the scores were level at 2-2.
Robert Lewandowski made no mistake from the spot to put Bayern Munich ahead in the huge top of the table clash and they held out for the victory.
After the match speaking to Viaplay Fotball, Bellingham slammed the referee.
He said: 'Well for me it wasn't (a penalty) you know. He (Hummels) is not even looking at the ball and he's fighting to get it.
'It hits him and I don't even think he's looking at the ball but you know you can look at a lot of the decisions in the game.
'You give a referee that has match-fixed before, the biggest game in Germany what do you expect?'
Bellingham's interview appeared to reference the 2005 German football match-fixing scandal.
Zwayer was banned for 6 months for his involvement which included accepting a €300 bribe from fellow referee Robert Hoyzer.
Erling Haaland also spoke to media after the game and had to hold himself from criticising the referee more than he did.
The striker felt that Dortmund should have been awarded a penalty for a challenge on Marco Reus and said the referee was 'arrogant' in his response when the striker asked him why he didn't check VAR.
Haaland said: I think it was a very scandal when it comes to the referee.'
He added: 'Clear penalty. I asked him why didn't you go and look and he said 'no need' like arrogant. I have to calm down a little bit now but yeah he was arrogant, I won't say more.'
Julian Brandt had given BVB the early lead, before he later went off after a clash of heads.
Lewandowski and Kingsley Coman turned the match around before half-time, with Haaland levelling matters just minutes after the restart.
Dortmund manager Marco Rose was sent off for dissent after his animated appeals on the touchline fell on deaf ears as tempers threatened to boil over after Bayern were awarded their match-winning penalty.
Bayern Munich now hold a four point lead over their rivals following their victory on Saturday night.
