Manchester United legend Roy Keane was shocked seeing United and Liverpool players hugging each other in the tunnel ahead of Sunday's 1-1 draw.
Roberto Firmino was seen speaking to and smiling with Andreas Pereira and Fred moments before the players walked out on the pitch.
"I'm disgusted with players [scenes in the tunnel]. You're going to war, they're hugging and kissing," Keane said on Sky Sports.
"Don't even look at the opposition. You're going into battle against them.
"The game hasn't changed that much, the players have changed. You're going to war against these players and they're hugging each other.
"Chat to them after the game, or don't even chat to them after the game."
