The first goalless stalemate since 2004 was a massive let-down after a huge build up. It leaves United four points adrift of leaders Chelsea, with City three points further back in fourth spot.
For that, Van der Sar blames City, who he felt did not even try to win the game.
"I don't think it was a good point for us," said the Dutch veteran. "The game was quite one-sided. We got the ball on the floor and passed it from player to player but we didn't create a lot because they shut us off well defensively.
"But City didn't really come forward and leave their defensive position. They were clearly aiming for a point and hoping for more whereas we really wanted to win and tried to play like that.
"It didn't really materialise for us but they were more defensive."
