Chelsea earned the point despite losing Moises Caicedo to a first-half red card.
Asked if the impressive result should see Chelsea regarded as being in the title race, Maresca replied: "I think, once again, sometimes I think I'm a little bit boring, but in terms of boring, I have to say, again, the same. If in February, March, we are where we are now, we're going to be for title.
"But we are still, you know, end of November, December. Now we are weeks away. Wednesday, that is a very difficult game. So, you need to be there every time, every time, every time. But for sure, you know, Arsenal tonight, Barcelona the other day, Liverpool, PSG, these kind of games, for sure, they give to the players, you know, the confidence to grow and to believe."
Asked what made him most pleased from the night, the Italian also said: "For sure, the effort of the players. Arsenal, they are top of Premier League, top of Champions League, best defenders in the Premier League, probably best defenders in Champions League. So, in this moment, they are the best team. And I think 11v11, we were better than them. Then with 10 players again, changed the dynamic. So, the effort from the players has been outstanding."
On the performances of goalkeeper Robert Sanchez and skipper Reece James, Maresca was particularly pleased.
He added, "Robert was very good. When you are with 10 players against Arsenal, for sure if you want to take a point or win the game, you need some special performance, like Robert, like Reece, as you said. So we are very happy with Robert's performance. Reece, now, his performance has been fantastic, top.
"Now, we have a game on Wednesday. For him, very good. We need to manage him, we need to control him, we need to control a little bit his situation. But he was very good tonight."
