Leicester secured their first win of the season as they hammered Nottingham Forest to dump their local rivals on the bottom of the Premier League and pile the pressure on manager Steve Cooper.
James Maddison scored twice and created another for substitute Patson Daka, with Harvey Barnes curling home a superb effort as Brendan Rodgers' side recorded their biggest home win since December.
For Forest, this first top flight East Midlands derby since 1999 was a night to forget.
Cooper's side never recovered from conceding twice in as many minutes not long after striker Taiwo Awoniyi had struck a post when clean through on the home goal.
