Sadio Mane may have gone on to score Liverpool’s second goal in an entertaining first half against Arsenal but debate was raging online as to whether he should have been on the field in the first place.
Just a few minutes into the game Mane ran down the right wing and led with the arm as he tried to shield the ball from Arsenal defender Kieran Tierney.
He ended up elbowing the Gunners star in the face and there was immediate uproar from the Arsenal players.

It was a huge decision for Craig Pawson early in the context of the game, which failed to fire until the Gunners scored the first goal in the 25th minute.
Pawson decided it was only worthy of a yellow card, electing to keep Mane on the field.
It proved a crucial call as Mane went on to later score his third goal of the season to help the Reds to a 2-1 halftime lead.
“It’s one of those where you are looking at an early duel in a game and you think the defender is coming to knock you,” Sky Sports’ Gary Neville said.
“But he’s got to be careful, Mane.
“It’s a real, obvious movement across to Tierney, a very definite movement.”
There was plenty of debate around the incident on social media too.

After an otherwise relatively uneventful start to the game it was Arsenal who took the lead against the run of play.
It came after Alexandre Lacazette took advantage of poor defending off a cross to score the opener.
Liverpool quickly hit back though as Mane picked up the scraps when Mohamed Salah’s initial shot was saved by Bernd Leno.
“Tierney cannot cope with the strength and directness of Salah,” Neville said.
“Leno gets a little bit on it, but not enough, and Salah’s mate Mane is there at the back post to gobble it up.”
By the 34th minute Liverpool had taken the lead as Andrew Robertson made up for his blunder in Arsenals’ opening goal.
He trapped Trent Alexander-Arnold’s cross on his chest before poking the ball through to score and resume normality after a rare error.
