Liverpool manager Jurgen Klopp says screaming in the fourth official's face against Chelsea looked worse than it was.
Manchester United boss Jose Mourinho's used the lenience of that incident as an example of how he's apparently unfairly targeted by referees.
He claims to have been threatened with a sending off during last night's draw with Hull.
"I know it looked not too nice, but it was not as bad as it looked," Klopp said on Thursday afternoon. "Of course, maybe I was lucky because the fourth official said what he said that he had never seen anything like that.
"But I said it and I think there are different ways to handle the situation. It's quite an emotional game and to switch off emotions in the right moment is not that simple... We are all different. Sometimes we get a fine, sometimes not.
"It's not that we want to do it or that it's a tactic."
He added: "It was worse with me when I was younger."
Mourinho cut a frustrated figure last night during his side's scoreless draw and told reporters after the game that if he had dared to do something like that, he would have been punished.
"I really don’t understand why you ask these kind of questions since the start of the season," he said at last night's press conference. "If I was in your place I wouldn’t ask the manager, I would just say and write what I see, what I think, what is my opinion.
"Game after game I would just write what is happening every game with us, if not every game almost every game. If I speak I am punished, I do not want to be punished."

He told reporters: "You simply have just to tell the truth, and if you go game after game with Manchester United and you see what happened here with Manchester City, what happened here with Burnley, what happened here with West Ham, what happened at Stoke, what happened almost everywhere, you do your job and you do your public service I think: tell the truth.
"If telling the truth is Manchester United didn’t play well in the first half, then so be it. But tell the truth, don’t ask me questions that I cannot answer."
