Erik ten Hag, the manager of Manchester United, said he would "deal with" Cristiano Ronaldo after the unused replacement left the field before Tottenham's victory.
Shortly after Ten Hag substituted Christian Eriksen and Anthony Elanga, Ronaldo, 37, exited the game.
“I will deal with that tomorrow, not today. We are now celebrating this victory,” said Ten Hag.
“I have seen him, but I haven’t spoken with him.”
Ronaldo decided to leave the bench early in Wednesday's 2-0 home victory even though United had only used three of their five allotted substitutions. He then vanished through the Old Trafford tunnel.
Three days prior, he expressed his annoyance at being replaced against Newcastle.
Following the scoreless tie on Sunday, Ten Hag stated that he had "no problem" with Ronaldo's negative response, but added that the Portuguese player must persuade him "he needs to stay on."
Gary Lineker, a former England striker, claimed that Ronaldo's actions unduly distracted from United's performance against Spurs.
“I’m sorry, that is unacceptable – it is so poor,” Lineker said on Wednesday’s Match of the Day.
Pundits Ashley Williams and Micah Richards agreed with Lineker.
“For one of the greats of the game to do that when your team are winning, making it about him, is disappointing,” said former England defender Richards.
Ex-Wales captain Williams added: “It was a great night for Manchester United and here we are again talking about Cristiano Ronaldo – even though he didn’t play.”
Speaking to BBC Radio 5 Live, former Manchester United goalkeeper Peter Schmeichel said Ronaldo would have been aware such behaviour would create “headlines”.
“It’s the first time I can say that I am disappointed with him. Normally I back him, I understand his situation,” Schmeichel said.
“We are in transition. Manchester United are now five managers down the road since Alex Ferguson,” he added. “We have got Erik ten Hag in now who has very clear ideas about the way he wants to play football. We need understanding and time from everyone.
“We don’t need distractions like that, and that’s a disappointment, I would say.”
