Leicester City are in complete control of their Premier League opening-day clash against Sunderland as they hold a 3-0 lead at half time.
The Black Cats had the first chance to threaten when Younes Kaboul met a corner and headed towards goal. Kasper Schmeichel made the save, but Jack Rodwell latched on to the rebound, but he could only guide his header into the hands of the Dane.
The Foxes took the lead in the 11th minute when they won a free kick down the left and Marc Albrighton lifted the ball into a dangerous area, and Jamie Vardy headed the ball past Costel Pantilimon with the aid of the post.
Leicester could have doubled their lead minutes later when Vardy raided down the flank and cut the ball into the box for Shinji Okazaki, but his strike was deflected behind for a corner.
The home side did extend their advantage in the 18th minute as Albrighton caused problems again, and his cross into the box was met by Mahrez who directed his header beyond the reach of Pantilimon.
Claudio Ranieri's men were handed the chance to add a third goal when Lee Cattermole brought down Mahrez in the box. The winger took the spot kick himself and dispatched the ball into the net.
Leicester could have made it four when Vardy was played behind the Sunderland defence, but Pantilimon made a fine stop to keep the scoreline down.
