Frank Lampard admits the two points dropped against Fulham could be critical for Chelsea.
"Without a doubt we should have won the game," Lampard said.
"We managed to get our nose in front and we felt comfortable in the game. Then we managed to get done on the set pieces and obviously there's frustration in the dressing room after the game.
"We dropped points against Fulham so Manchester United have a chance to go above us if they win all of their games in hand so that brings a lot of importance."
