Liverpool opened the scoring against Fulham with a goal that further intensified the debate surrounding VAR’s absence in the Premier League.Aleksandar Mitrovic headed the ball into the back of the net but his effort was ruled out for offside.Then, Liverpool launched a quick attack, Mohamed Salah burst through on goal and slotted the ball away.There were just 13 seconds between Mitrovic’s goal being disallowed and Salah scoring.And adding to Fulham’s frustrations is the fact that the Mitrovic call was incredibly tight - the referee’s assistant was unsighted, and probably guessed.This incident, like Charlie Austin’s disallowed goal in Southampton’s 1-1 draw against Watford on Saturday, only serves to increase the need for VAR in England’s top flight.While much of the focus centred on the offside call, replays also showed that the ball wasn’t stationary when Alisson Becker restarted play.

The ball was rolling

The Brazilian dropped the ball to the floor and played a quick pass to Trent Alexander-Arnold - but the ball was still rolling when he passed it.

And rules state that the ball must be stationary.

“The ball must be stationary and the kicker must not touch the ball again until it has touched another player,” the official IFAB laws surrounding free-kicks state.

Of course, it was incredibly tough for the referee to spot that. But it will only add to Fulham’s anger.

Football fans reacted on Twitter after spotting what happened.

Unfortunately for Fulham, they lost concentration. And that's something you just can't do against Liverpool.

Salah completed a swift attack for his sixth goal in the league this season.

Xherdan Shaqiri made it 2-0 with a fine finish in the second half as Jurgen Klopp's side responded in style to the disappointing defeat to Red Star Belgrade.

As for Fulham, they remain rooted to the bottom of the Premier League.

They will complain about Liverpool's first goal, but they really need to start picking up points.
