Manchester United boss Jose Mourinho defended Jurgen Klopp after the Liverpool manager left his technical area to fume at defender Dejan Lovren on Saturday.
Klopp charged down the Old Trafford touch line to berate Lovren late in his side's 2-1 defeat.
The German avoided being sent off by Craig Pawson, and Mourinho praised the referee for his decision.
"Probably you are not expecting my answer — I'm happy with the decision," Mourinho said during his post-match news conference.
"Because [Klopp] was not speaking against the referee. He was upset with a player and the same happened to me against Crystal Palace, where I was upset with my player and therefore they [the officials] understood that too.
"I think [fourth official] Martin Atkinson, after so many years of this, made the right decision. I saw it. [Klopp] was very upset with his player and not at the referee.
"If you leave the technical area by a couple of metres — or in this case, 20 metres — but to speak to your own player and not to complain about the referee's decision, they made the right decision."
Marcus Rashford scored a pair of first-half goals as United opened up a four-point lead in second on the table, while Liverpool fell to fourth.
