David Luiz believes the referee was harsh to award a penalty against him during his Arsenal side's 3-1 defeat to Liverpool .
Luiz was adjudged to have pulled Mohamed Salah's shirt in the box early in the second-half by referee Anthony Taylor, and Salah scored the resulting penalty to put his side 2-0 up.
The Brazilian defender said he discussed the incident with the Liverpool forward, and that Salah agreed the penalty seemed soft.
Speaking to Sky Sports following the match Luiz said: "I think the second goal, the penalty, killed the game.
"If I pull your shirt or put my hand on your shirt it’s totally different, the power is different. VAR is difficult for them they cannot see the power. It depends on the interpretation. I spoke with Momo he said, 'I didn’t feel that'."
Luiz also appeared to be at fault for Salah's second goal which put Liverpool 3-0 up as he allowed the Egyptian to run past him with ease.
But with the player having been booked for the penalty he conceded he explained: "For the third goal I could not make the foul and put my team in trouble with 10 men.
"So I think I conditioned my game after that, it was more difficult, but the team fight until the end."
The result was a rude awakening for Arsenal, who had won their opening two matches against Newcastle and Burnley .
Manager Unai Emery appeared to be looking on the positive side after the game, however, saying: "After 2-0 our reaction was good. We needed to attack and take a different moment in the match. We are disappointed we lost 3-1 but watching some players we can be optimistic."
They will look to get back to winning ways when they take on bitter rivals and fellow top four challengers Tottenham next Sunday.
