The sense of sheer animosity between Manchester United legend Gary Neville and Liverpool supporters has always been substantial, so it may not help matters when Reds fans hear the former right-back say he tried to get their heroes sent off during games.
Ahead of Liverpool and United's clash this Monday night, Neville sat down with Sky Sports colleague - and former sworn enemy - Jamie Carragher for a forthright discussion about one particular incident: Javier Mascherano's foul on Antonio Valencia back in March 2010.
Fernando Torres had put Rafael Benitez's men ahead with a fantastic header before the Argentine hauled down the United winger in the penalty area. While the Liverpool fans remonstrated wildly that initial contact was made outside the area, Neville tried to influence referee Howard Webb's decision.
"Mascherano had pulled down or tripped someone, I can't remember who he tripped,"Neville told Carragher onSky Sports.
"I went straight to the referee because one of the big things in these games is if you can get someone sent off, you do it straight away. He [Carragher] knew what I was doing and he would've done the same, by the way. In those days, you would go to the referee, talk to him and say 'are you going to make a decision?'
"I was trying to stop him getting to the referee because I knew what was coming," Carragher added.

"Part of the big games is influencing the referee," Neville explained. "You had to. Arsenal did it, Liverpool did it, we did it. Other clubs like Chelsea did it and I genuinely believe you could influence them. Not in a way that makes them a cheat or dishonest, no, but just that the pressure of being in Anfield or Old Trafford with that weight, it's not easy.
"It can't be easy to cope for one man to think they don't know who is telling them the truth. He's saying one thing, I'm saying exactly the opposite, the fans are saying something different, the managers are all up there and he's got to keep cold and make a decision and you're trying to influence that.
"It wasn't a massive part of the game, but it was part of the game that was there and this incident was over influencing the referee."
