Back in 2010.
The Argentine striker was actually the match-winner, scoring both goals and the celebration for his first was pretty provocative towards the United fans, cupping his ears as he ran to the away end.
Neville was not pleased and reacted rather harshly.
NEVILLE FLIPS THE BIRD
Naturally, United manager Sir Alex Ferguson was asked about the incident after previously stating that he had no problems with Tevez's celebration against his side.
FERGIE'S STANCE
When asked about the row, Fergie replied in typical fashion, saying, per
Guardian: "I am not interested," he said. "Carlos Tevez is not our player anymore and I have nothing to say about it at all.
"Players argue with each other all the time. They have a go at each other time and time again. It is not an issue for us. We move on."
If Fergie had had any say, Alli's little misdemeanour would have been swept under the rug.
