Bradford were woeful last weekend when going down 2-1 at home to Walsall yet they performed admirably against a Foxes side vying with Portsmouth for top spot in the Division One table.
"I've said to the players why is it you cannot give me the level of performance like you did here on a regular basis?" said Law.
"If we had put in half the performance on Saturday as we did here then the game against Walsall would not have been a competition.
"But that has been our problem this season, our inability to perform against the lesser teams around us."
