Conte, who also suggested Luiz was tripped by Alexis Sanchez in the build-up to the foul, telling Sky Sports: "I don't talk about the referees, but the only thing I can say is we need to see what happened before the tackle".
Quite how Arsenal failed to score with four minutes of the half remaining is an understatement First Aaron Ramsey raced straight through the Chelsea rearguard but saw his shot, rebound off Courtois left post.
Arguably they should at least have got on the scoreboard but their record signing Alexandre Lacazette missed an open goal in the first-half.
Luiz was shown a straight red card in the closing stages of the London derby by Michael Oliver having been adjudged to have jumped into a challenge on Arsenal full-back Saed Kolasinac. "But sometimes, it is very odd to finish for the third time in a row with 10 men against Arsenal".
"It was about mentality and a response from our last away game", said Wenger.
"For sure it's odd". Referee Michael Oliver did not take time to think about it, and decided straight away it was a risky tackle and thus brandished the Brazil defender with a straight red card. A unusual situation. Yes. "Sometimes the opponents deserve a red card but, instead, they carry on playing with 11 men".
"Both teams are great teams and I think it is a good draw".
"In the end, we'll try to pay more attention in the future".
Ramsey said afterwards: "I think we needed that, after Liverpool".
Danny Welbeck is facing yet another lengthy absence from the Arsenal team after limping off in the 73rd minute of their goalless draw against Chelsea with a suspected groin tear.
