Leicester recorded an eighth successive victory in the league to move eight points clear at the top of the table with a 1-0 win against Sunderland as James Justin's first-half header proved decisive.
Justin rose highest to head home Kiernan Dewsbury-Hall's corner after 12 minutes and secure the points as the full-back scored his first league goal for the club in over two years.
The Foxes hit a post twice in the first half and missed a number of chances to double their lead throughout but did enough to secure a 12th win from 13 league matches to continue their stunning start to the season.
