Leicester had to twice come from behind to get a point.
Pearson said: "Yes, we came from behind twice and had lots of opportunities later on to win it but I am disappointed to drop two points at home.
"The opposition have come here again to set up behind the ball, but we've got to be prepared to find a way to unlock that door.
"I can't be too disappointed though because we've still lost only once so far this season but when you score two goals at home that should be enough to win - we let the opposition score twice and that speaks for itself."
