Man United midfielder Scott McTominay was seen shouting something in the direction of the Liverpool fans after the full-time whistle on Sunday and fans think they know what.
United beat their rivals 4-3 in an epic FA Cup quarter-final at Old Trafford, Amad Diallo scoring a dramatic winner in the final minute of extra-time.
McTominay opened the scoring on the day and had a few choice words for the travelling away fans.
The midfielder jumped into the arms of goalkeeper Andre Onana and pointed to the Reds supporters before appearing to say 'f*** you'.
Viewers quickly took to social media to share the clip and they were in agreement that that is indeed what he said.
'McTominay telling the Liverpool end 'f*** you' at the end of the game', wrote one on X while another said 'McTominay not holding back on the Scousers at the end of the game'.
Another posted: 'Scott McTominay saying f*** you to the Liverpool fans and Andre Onana giving it back after he (no doubt) copped it all second half and in extra time. Love that, these videos are so good.'
McTominay gave his side the perfect start to the game but the Reds hit back through Alexis Mac Allister and Mo Salah.
Under pressure Erik ten Hag’s side offered little in response, but substitute Antony managed to level against the run of play in the 87th minute.
Liverpool sub Harvey Elliott put the Reds back in front in the 105th-minute but Marcus Rashford restored parity just seven minutes later before Diallo caused pandemonium in the stands at the death.
