Kelechi Iheanacho scored his first Premier League hat-trick as rampant Leicester put sorry Sheffield United to the sword at the King Power Stadium.
Ayoze Perez's strike and an Ethan Ampadu own goal sealed a 5-0 success for the Foxes which saw them return to second place in the table, before Manchester United's game against West Ham later.
For the Blades, it rounded off a difficult week which had seen the departure of manager Chris Wilder the day before the match.
Sunday brought the day United fans never wanted to contemplate – the first game after the Wilder era.
Under-23s coach Paul Heckingbottom took charge on Sunday but it was the same old story for the Blades, as they struggled to make an impression or trouble Leicester as an attacking threat. The Foxes dominated and could have won by a bigger margin.
Jamie Vardy dragged a 20-yard shot wide after eight minutes before Perez's glancing header was touched on to the post by Aaron Ramsdale shortly afterwards. Ramsdale then blocked a low shot from Vardy with his legs.
Leicester made the breakthrough six minutes before half-time. Some sharp, incisive passing between Youri Tielemans and Perez resulted in Vardy getting in behind the Blades defence down the left-hand side. His low cross left Iheanacho with a simple tap-in from close range.
Leicester doubled their lead after 64 minutes. Marc Albrighton led a counter-attack after the Blades had a free-kick in a dangerous position, and teed-up Perez who found the bottom corner with a strike from the edge of the penalty area.
Five minutes later, it was 3-0 to the Foxes. Vardy was the provider for Iheanacho once more, with the striker guiding the ball past goalkeeper Ramsdale from 12 yards.
Iheanacho completed his hat-trick after 78 minutes, driving a low shot from 25 yards beyond Ramsdale and into the bottom corner of the net.
It was the Nigerian striker's first Premier League treble, and he looked quite emotional as the game restarted.
It got worse for the Blades two minutes later when Vardy's shot from the left side of the penalty area, which looked to be heading wide, ended up in the back of the net via the outstretched leg of Ampadu.
It should have been six, and another goal for Iheanacho, but his shot was deflected over the crossbar by George Baldock.
"I don't know how to express this, I've been waiting for this day to come. I'm grateful to God, my teammates and my manager for helping me grow," said Iheanacho after the match when top scorer Vardy failed to find the net.
"Playing with him [Vardy] is a joy, he makes so much space for me. I'm really happy, I'm delighted. Even when he's not scoring he's helping the team to win.
"It was the first win at home for a while and it's a clean sheet as well so we're all really happy."
