Marc Albrighton’s deflected strike earned Leicester a 2-1 victory on Saturday that left Norwich without a point in its three games since returning to the Premier League.
Jamie Vardy curled in the opener for Leicester in the eighth minute but it was cancelled out by Teemu Pukki netting a penalty in the 44th after Caglar Soyuncu slid in to foul Pierre Lees-Melou.
Daniel Farke’s hosts had looked the more likely to find a winner but Albrighton punished the Canaries in the 76th after being set up by Vardy.
Celebrations by Norwich late on were cut short when Kenny McLean’s header was ruled out for offside. Leicester moved onto six points after three games.
