The Blues managed 21 attempts on goal in the London derby, but were unable to find the breakthrough over 90 minutes.
Speaking after the game, Maresca said that it was a good point for the Blues, who remain fourth in the league standings.
He said: "When you are not able to win, it's important you don't lose, you take the point and you move the table."
With the draw, Chelsea are fourth in the standings with 53 points, one ahead of Manchester City and two in front of Aston Villa.
However, Newcastle United, who are seventh in the table, are just three points behind the Blues with two games in hand.
The race for the Champions League spots could go down to the wire. Chelsea must keep winning to avoid losing out.
The Blues will entertain Ipswich Town in their next league game.
