Police were forced to intervene during Liverpool's 1-0 win against Sunderland last night after Jurgen Klopp was left fuming following Jeremain Lens' strong tackle on Mamadou Sakho.
The Liverpool boss was incensed following Lens' tackle on his defender in the 85th minute, which earned a booking from referee Kevin Friend, and was involved in an angry confrontation with rival boss Sam Allardyce in the aftermath. Police stepped in to break up the pair, while both Liverpool and Sunderland's coaching teams were also involved.
Allardyce dismissed the controversy and accused the German boss of being 'soft', however Klopp was adamant that Lens should have seen red.
He said: "Of course I was angry. I don’t want to say, 'Come on, give him a red card'. I have no problem with the player. But when you go in like that, anything can happen.
"For me, that’s a red card, finished. My staff were emotional and the staff of Sunderland were emotional."
Klopp has already been involved in more than a few touchline bust ups in his short time in the Premier League so far, having clashed with a member of Chelsea's coaching staff, and West Brom boss Tony Pulis.
"He’s a soft German if he thinks that’s a red," Allardyce said of the incident. "It’s a yellow, it’s a foul. There was then some foul and abusive language towards my staff that I did not like. But we shook hands afterwards and that’s what you’ve got to do."
Sakho didn't seem to bear any ill-feeling towards Lens after the game, and posed with a Sunderland shirt alongside Black Cats' midfielder Yann M'vila on Instagram.
Christian Benteke scored the winner at the Stadium of Light last night, just 22 seconds after half-time to help Liverpool up to seventh in the Premier League - one point ahead of West Ham, who they face on January 2.
