Goals from Kelechi Iheanacho and Demarai Gray handed West Ham United a second consecutive 2-1 defeat, with Leicester City leaving London Stadium with all three points.
Lukasz Fabianski, returning after a three month absence, gave away a penalty early in the game but redeemed himself immediately by saving Gray's effort, but the Foxes still took the lead through Iheanacho's close-range header.
Pablo Fornals netted his first Premier League goal for the Hammers with a tidy finish to level the match prior to half-time, but Gray's sweeping effort meant West Ham were beaten in the Saturday evening fixture
