Manchester City manager Pep Guardiola appeared to suggest referees are biased towards Liverpool at Anfield after seeing his side beaten 1-0 on Merseyside.
The reigning Premier League champions believed they had taken the lead in the second half when Phil Foden fired in from close range. But referee Anthony Taylor consulted the pitchside monitor and opted to disallow the goal due to a foul from Erling Haaland in the build-up.
Liverpool went on to take victory as Mohamed Salah scored a sensational winner amid jubilant scenes at Anfield. But Guardiola was furious as he suggested the game being played at Liverpool's home stadium meant the decision went against them.

He also claimed Liverpool fans threw coins at him in the aftermath but stated he was not struck by the objects.
"This is Anfield, every time you come here lately unfortunately this is Anfield," Guardiola told BBC Radio 5 Live.
"We played a really good game but this is a game where there are really fine margins and the mistakes are punished. We made a mistake and we cannot concede and that's why we lost the game.
"We played to beat Liverpool today, definitely we played for that. After 1-0 the crowd shouted but we shouted more on the pitch.
"The referee said played on, played on, played on, there were a thousand million fouls like this and this one is because we scored a goal. So they disallowed because we scored a goal, otherwise it would not have been disallowed.
"We lost because we make a mistake but this is Anfield. The crowd tried [to throw coins/objects] but they didn't touch me. Maybe next time they will be better."
Speaking to BBC Match of the Day, Guardiola added: "This is Anfield, in the Champions League three or four years ago, and we come here most of the time it happens.
"We have to make a perfect game and we didn't, we made a mistake, hopefully in the future we can learn but teams like this, [competing] in the Champions League, it is so tight and they punish you.
"The referee says play on, play on, play on, how many thousand million fouls he has almost given? But the goal was not given. That is the question, so when the referee decides to speak to the mangers, to Jurgen Klopp, to my assistant coach and say 'I am going to be clear, it happens all the time in that way,' then you cannot disallow the goal. But if you decide in the first minute fault, fault, fault... But you know, this is Anfield."
Despite Guardiola's protestations, Gary Neville felt the decision was correct as he watched replays on co-commentary.
Neville said on Sky Sports: " Pep’s going mad, whatever happens coming out of this, I imagine it’s going to be cancelled will mean this atmosphere will be electric and turned up.
" There’s that tug on the shirt from Haaland on Fabinho there, that’s why the goals going to be disallowed. He’s been here before, it’s just the tug of the shirt his right hand. I have to say he holds on for too long to pull Fabinho down. I think it’s the right decision. "
