Manchester United striker Rasmus Hojlund aimed a cheeky dig at Manchester City's Kyle Walker following the 2-1 derby win. The two men collided just before half-time after the Englishman appeared to push the Dane.
Hojlund reacted furiously and confronted Walker, with the pair locking heads. The Englishman then theatrically fell to the ground, perhaps to get the 21-year-old sent off.
However, VAR checked the incident and a red card was ruled out as Hojlund and Walker were handed yellow cards by referee Anthony Taylor.
However, it was Hojlund who would have the last laugh. Manchester City had gone ahead in the 36th minute through a Josko Gvardiol goal and it long appeared that the Cityzens would pick up all three points.
However, Matheus Nunes' clumsy challenge on Amad Diallo gifted Manchester United a penalty late in the second half. Bruno Fernandes stepped up in the 88th minute to make it 1-1.
Amad then latched on to a superb long ball from Lisandro Martinez, rounded Ederson and scored the winner in the 90th minute. After the game, Hojlund shared a picture of his confrontation with Walker on social media, hinting that the Englishman deserves an Oscar.
"Manchester is red; Violets are blue; What a brilliant performance; But the Oscar goes to…" wrote Hojlund.
The win sees Manchester United stay 13th in the Premier League, but they are now within five points of fifth-placed Manchester City.
Who was Manchester United's hero in the Manchester Derby?

Amad Diallo was key to Manchester United's triumph over their bitter rivals on Sunday at the Etihad. The 22-year-old completed 94% of his passes and won seven of his 10 duels on the night.
Amad completed five of an attempted eight dribbles and registered four shots. He also won a penalty and scored the winner.
The Ivorian had struggled for chances under Erik ten Hag but has come into his own under Ruben Amorim. Since the Portuguese took charge of the Red Devils, Amad has registered five assists and one goal and has certainly been one of the club's best players.
The Ivorian initially started as the right wing-back in Amorim's 3-4-3 system but has been pushed forward as a wide No. 10s in the last two games. Amad hasn't disappointed in either position and looks set to be a key player under the Portuguese. Manchester United signed him from Atalanta in 2020 reportedly for an initial £19m fee.
