Virgil van Dijk's last-gasp winner sent Anfield into frenzy and Simeone was quickly goaded into a reaction by one home supporter's taunts on the sidelines alongside his staff, who were equally frustrated in the final few minutes of the game.
Simeone was subsequently sent off for his actions and had to be forced back down the tunnel, much to the delight of Liverpool fans. The fan, Jonny Poulter, has now spoken about the incident which made him viral amongst football fans overnight.
"Something I want to get off my chest here in regards to what happened last night with Simeone. I think he's a bit of a coward.
"When he went in and done his press conference after the game, the Spanish media has asked him what was said - if it was racist, if it was regarding the Falklands War or all this rubbish.
"There was nothing racist said by me or anyone else. There was never a mention of the Falklands War by me or anyone else.
"But the fact that he was asked it and he didn't answer the question, and he just got up and walked out, has left it open to speculation for the world.
"I’ve had messages on every platform of people saying, 'What did you say?' I never said anything apart from, 'F*** off, we've won', as you do.
"That is what he did to us when they scored the equaliser, his assistant manager giving it in front of us. He was getting called a s***house and whatever else. His assistant manager, who came over and spat at me… yeah."
Liverpool have maintained a 100% win record across all competitions, with four wins in the Premier League before their Champions League opener.
However, late winners such as these are unsustainable and as the Merseyside derby approaches, the Reds will have to up their performance, otherwise three points could be dropped.
