David Luiz was sent off on his Stamford Bridge homecoming after his tackle on youngster Tammy Abraham, with Jorginho converting the resulting penalty.
Gabriel Martinelli struck the equalizer for the visitors, before Cesar Azpilicueta’s 84th minute strike was cancelled out by Hector Bellerin three minutes later.
Arteta was speaking to the media after the game and insists the players showed great character against a team of Chelsea’s standard.
"I am very pleased with the reaction,” the Spanish coach told BBC MOTD.
“To do that against this kind of opponent in this stadium, I really value. The way they have done it, with the spirit they have done it, that's great.”
"When someone makes a mistake you expect your team-mates to stand up and they showed that belief, I was really impressed with that.”
"I wasn't here a couple of weeks ago but what I am demanding every day they are trying their best to do it. Some are playing in different positions.”
"The togetherness and leadership they showed, this is what I wanted to see.”
"It's very important for the development. We are in the process and are going in the right direction but I think tonight is a special night for everybody.”
"Granit [Xhaka] is - the way he trains every day - his attitude is incredible. I am very pleased with him in that position, the way he came in. I wasn't expecting Hector Bellerin to score with his left foot but he is fighting hard."
