Roy Keane slated Nemanja Matic for his post-match interview after Manchester United's 1-1 draw with Chelsea at Old Trafford on Thursday night.
United avoided a third straight defeat after Cristiano Ronaldo's stunner immediately cancelled out a similarly impressive Marcos Alonso strike.
The glorious Ronaldo effort was his 23rd of the season and was assisted by Matic, who produced a sumptuous scooped pass against his ex employers.

Matic has already announced he will be leaving United after five years and said the Red Devils "will always be in my heart" in his interview after the game.
But he also said the same about Chelsea and Benfica, his other former clubs. That seriously irked Keane, who wasn't a fan of Matic's comments.
"Where’s the standards at the club?" Keane asked on Sky Sports.
"Matic’s talking about I’m leaving, I’ve had a great time, Man United will always be in my heart, oh and Chelsea as well, oh and Benfica don’t forget them, they all can’t be in your heart."
Host Dave Jones chimed in after Keane had finished, joking that Matic has a "big heart".
Jamie Redknapp was also in the studio and the whole trio were in hysterics.
Matic signed for United from Chelsea in a £40 million move in 2017, linking up with Jose Mourinho for the second time.
The 33-year-old has made 187 appearances for the club but on 15 April, confirmed he would be leaving a year prior to the expiration of his contract.
In the controversial Sky interview which Keane took issue with, Matic said: "It was a pleasure, an honour, to play at Old Trafford for the five years.
"Three more games to play and United will stay forever in my heart - together of course with Chelsea as I also played for Chelsea.
"For me, it was an honour to be part of everything."
In typical Keane fashion, the former United captain was highly critical after seeing Marcus Rashford smiling during the warm-ups.
"Every time I see Marcus getting warmed up, he's always smiling," the 50-year-old said on Sky Sports.
"I don't like players smiling too much."
