Nigerian international Wilfred Ndidi was on target as Leicester beat troubled Chelsea to go top of the Premier League.
The Foxes took a sixth-minute lead when the midfielder fired a shot into the net following a corner.
James Maddison made it 2-0 worse for the Blues four minutes to halftime after the video referee turned down the visitor’s agitation for a penalty.
The win puts Leicester one point ahead of Manchester United, who have a game in hand.
Chelsea are eighth. The London club have won only one of their past five Premier League games.
