Luke Littler has fired shots at Douglas Luiz after Manchester United's 2-1 victory over Aston Villa on Sunday.
The Red Devils secured all three points courtesy of goals from Rasmus Hojlund and Scott McTominay, with Luiz on target for the home side.
After the Brazilian international levelled for Villa, he performed a shimmy on the pitch right in front of Raphael Varane and Andre Onana.
Varane wasn't happy, with the former Real Madrid star raising his arms in protest.

United ultimately got the last laugh following McTominay's thunderbolt header, which came after a sensational cross from Diogo Dalot.
And Littler has now stuck the knife into Luiz on social media.
"Karma is real," he wrote on his Instagram story.
Luiz's actions seemed to spark United into life, with the Red Devils struggling once the hosts drew level.
Their victory was a huge one, however, and means Erik ten Hag's side are just five points behind Villa in the race for Champions League football next season.
Littler was jubilant after the result and also said on the social media website: "Yanited, Yanited, Yanited!"
Ten Hag was also asked about Luiz's shimmy after the result in the Midlands.
And the Dutchman admitted it may have fuelled his side on to victory, saying: "I don't have an opinion about that.
"I haven’t spoken to the players. Maybe it fuelled them, I don't know.
"I don’t think it is important. It is about us, we have to think about our game and not the opposition."
Ten Hag also said the win was 'massive' for his team, with the 54-year-old adding: “It was massive. It's a massive win for us.
"So, we get closer. And that was the aim for today and was absolutely our target.
"And we did it. And I think also the way we did it, I think I liked it, and of course, I liked especially the first 20 minutes.
"And when we are dictating the game, after I think we are dropping a little bit too much.
"We had our moments in the counter attacks, but yeah, I think then at 1-1, to fight back, we are really happy for today.”

Villa boss Unai Emery, meanwhile, said his players were 'frustrated' after being unable to get anything from the match.
“We speak about the result and we are frustrated,” he said.
“We were being successful here at home in a lot of matches, playing a lot of matches worse than we played tonight against Manchester United.
“We created chances but we weren’t clinical. Their goalkeeper played a fantastic match and we lost a very good opportunity.
“This is the way to build our structure stronger and to try and control the game in the structure we are progressively trying to build. We did it.

“The plan before the match we were speaking about in the dressing room and the players did it.
"Sometimes it was goalkeeper, sometimes we weren’t clinical, but we controlled the game and avoided the transitions.
“We conceded a few chances to score but they are Manchester United and they have very good players.
"We have to be proud of our work, proud of our supporters, and we are fifth in the league.
“We lost a very good opportunity today to do a bigger gap with them but we keep going.”
