Raphael Varane wound up Luton Town fans by blowing them a kiss after Manchester United's 2-1 win at Kenilworth Road on Sunday.
Rasmus Hojlund scored twice in the opening seven minutes to put Erik Ten Hag's side comfortably ahead, and whilst Carlton Morris got a 14th goal for the Hatters, they were unable to find a second, and Man United saw out the game.
Varane was one of Manchester United's central defenders who was able to snuff out the attacking threat from Luton as they searched for their equalizer.
His crucial 31st-minute block denied Luton an opportunity to level following Harry Maguire's mistake.
The Frenchman provided another reminder that Man United would be wise to extend his contract beyond the end of the season, having been at the club since 2021.
When the match was over, Varane blew a kiss to the Luton Town fans as he walked down the tunnel - which did not impress the home supporters nearby.
They reacted furiously to the action of Varane, with one even hitting the tunnel, and others gesturing in anger while the French defender disappeared into the changing room.
There were jeers and whistles from around Kenilworth Road as the officials and other Man United players made their way off the pitch at the end of the game.
It followed a match which saw Manchester United captain Bruno Fernandes taunted by Luton fans.
Hojlund's goals made him the youngest player ever to score in six consecutive Premier League games, 14 days after his 21st birthday - and afterward, manager Erik ten Hag said that the Dane was a 'fighter' building his confidence with more goals.
The victory helped ten Hag's side to close the gap on the teams in front of them in the race for the Champions League spots.
Sunday's match at Kenilworth Road was attended by pop star Harry Styles, who was spotted wearing Manchester United kit during his time with One Direction.
Styles share an unlikely friendship with Rio Ferdinand and enjoyed a kickabout with Man United legend David Beckham and his son Brooklyn in 2015.
