Arsenal went on to lose 2-1. Ruben Neves scored the resulting penalty before Joao Moutinho netted a 30-yard screamer just after half-time.

Luiz's red card was the turning point and Mikel Arteta vented his frustration about the decision after the game.

"I’ve just seen the replay ten times in five different angles and I cannot see any contact," the Spaniard said, per the Metro.

"If I’m sitting here now I would say yes [to an appeal]. We have to speak with legal at the club and see what the best thing is to do.

"If there is any contact it’s him with David. I don’t know if they have a different angle to what they have or you have.

"Those big decisions are like that but it’s nothing I can change at the moment.

"It was a big decision and they can justify if they got it right then I put my hands up and apologise.

"The only thing I’m saying is I’m sitting here and I cannot see any contact and it’s really frustrating because it’s a big moment in the game."
