Mo Salah and Jurgen Klopp were involved in a furious row after Liverpool conceded to West Ham on Saturday.
Having been 1-0 down to a Jarrod Bowen header, Liverpool turned things around following a strike from Andy Robertson and a comical own goal from Alphonse Areola.
But then Michail Antonio headed home an equaliser for the Hammers to make it 2-2 at the London Stadium.
Mo Salah was dropped for the game after a disappointing showing in the 2-0 Merseyside derby defeat to Everton and he was preparing to enter the fray just as West Ham levelled.

While waiting to come on, he was seen in a heated and animated exchange with Klopp - with fellow sub Darwin Nunez having to calm things down.
It's not known exactly what was said between the pair but Salah had looked unhappy in the warm-up after being omitted from the starting XI.
As footage showed on the TNT Sports feed, Salah was seen throwing his hands and doing plenty of pointing after Klopp had said something.

Nunez then came over to push Salah away but the former Chelsea winger was clearly still seething.
Liverpool's talisman was unable to bag a winner for the Reds, who appear to have lost ground on title rivals Arsenal and Manchester City after winning just one game in their last five league outings.
Both Arsenal and City are in action on Sunday against Spurs and Nottingham Forest respectively, with Liverpool requiring almighty capitulations from the pair to have a chance of winning a second Premier League.

Salah applauded the travelling away supporters after the final before exiting down the tunnel, with Klopp sure to be asked about their flare-up in his post-match media duties.
Liverpool return to action against Spurs on 5 May, before finishing up with games against Aston Villa and Wolves.
