Chelsea 0 Arsenal 0
Chelsea head coach Antonio Conte felt referee Michael Oliver should have stopped play for a foul on David Luiz before the defender was sent off in yesterday's goalless draw with Arsenal.
Luiz was shown a straight red card late on for a poor challenge on Sead Kolasinac which saw both benches rise to their feet.
The Brazil defender, who had earlier been booked for catching Laurent Koscielny with an overhead kick, now faces a three-match suspension which would include the Premier League visit of Manchester City.
Conte believes Luiz was fouled by Alexis Sanchez prior to the challenge which saw him dismissed three minutes from time.
Conte said: "It's very important to see what happened before the David Luiz tackle. For sure there was a foul.
"The referee has to use the whistle. If he stops the play before I think it (wouldn't) happen."
Arsenal boss Arsene Wenger felt it was the correct decision to dismiss Luiz.
He said: "It was excessive force, yes. I think Kolasinac was not completely on his feet.
"Even Luiz will accept there was a big distance and he went in too strong."
Chelsea may yet appeal against the length of the suspension, which will also see Luiz miss Wednesday's Carabao Cup clash with Nottingham Forest and next Saturday's league trip to Stoke.
The Blues have now received five red cards in their last eight games, including May's FA Cup final loss to Arsenal, with four coming this season.
Conte added: "I hope to be more lucky with the referee's decision, for us and also for the opponent."
Chelsea had scored in their previous 23 Premier League games at Stamford Bridge, but were held by an Arsenal team which ended a five-match losing streak at the Bridge in the first goalless draw between the sides in more than 12 years.
The Gunners had the better chances, the best when Alexandre Lacazette shot wide after Aaron Ramsey had hit the post, while Shkodran Mustafi had a goal ruled out correctly for offside.
Danny Welbeck, who went off with a groin injury, headed wide in a first half which saw Petr Cech save well from Pedro.
The Spaniard went off with an ankle injury at half-time.
Arsenal still have not won in the Premier League at Stamford Bridge since October 2011.
Wenger's men are still chasing a first away win against the established top six since January 2015 at City, but this was much improved following the 4-0 loss at Liverpool.
Wenger said: "It's true you have to accept when you deliver the type of performance we had at Liverpool that you are criticised.
"It was vital for us, even above the result, to come out with a solid performance.
"It was a battle all over the pitch. We responded well.
"I feel it's a deserved point."Chelsea: Courtois, Azpilicueta, Cahill, Luiz, Moses, Kante, Fabregas, Alonso, Willian (Hazard, 69 mins), Pedro (Bakayoko, 46 mins), Morata (Christensen, 88 mins).
