Jose Mourinho says he is unhappy with the lack of consistency of the referees after Liverpool's win over Manchester City on Sunday.
Liverpool beat the city 3-1 at Anfield thanks to goals from Fabinho, Mohamed Salah and Sadio Mane.
Bernardo Silva reduced the score to 3-0, but that was not enough to provoke a spectacular return.
Fabinho's first match was controversial as City thought they should have received a penalty before Liverpool counterattacked and scored.
The ball hit the right back Reds Trent Alexander-Arnold on the arm, but VAR felt that he was not in an unnatural position.
The boss of the city, Pep Guardiola, was furious with this decision and clearly expressed his feelings to referee Michael Oliver after the match.
Jose Mourinho said the worst part of this decision was that another day a penalty would have been imposed.
"I think we've talked enough about it and I think the main question is just consistency," Mourinho told Sky Sports.
"That's what really annoys me in the game. Right now, this weekend is not a penalty and next week it will be a penalty. For me, this is the crucial point.
"The game was so good and there is so much to say about the game that I think it's enough."
Mourinho admits that Manchester City could have prevented Fabinho's goal, but praised Liverpool's counterattack.
"Yes of course [the city could have prevented the goal], there is no doubt about it," he added.
"And I think everyone knows the strength of Liverpool in these situations, everyone knows how they play and how they manage to leave Salah and Mane in privileged positions for these transitions, everyone knows positions that they like to attack and you see the way forward they score both goals, the second and the third.
"The city is too beautiful to cry now for a week about an incident, it should also focus on the game, on what it could do better."
