Sheffield United produced one of their best displays of the season as they outplayed Frank Lampard's Coventry City at Bramall Lane to return to the top of the Championship table.
Former Sky Blues midfielder Gus Hamer put the Blades ahead with an excellent free-kick before top scorer Tyrese Campbell made it 2-0 before the break with his 11th goal of the season.
Back-to-form Rhian Brewster then followed up his Steel City derby winner prior to the international break by scoring the hosts' third in the second half - the former Liverpool youngster's first goal at Bramall Lane since January 2022.
A dismal evening for the Sky Blues at least had a silver lining when substitute Jack Rudoni scrambled in a consolation goal from close range.
The Blades go three points clear of Leeds United, who will be back on top if they win at home to Swansea City on Saturday afternoon, and five ahead of third-placed Burnley.
Fifth-placed Coventry are at risk of being displaced in the top six - but only if both West Bromwich Albion and Bristol City win, at Norwich and Burnley respectively.
City's second defeat in three games came at the further cost of losing Swedish goalkeeper Oliver Dovin, who was stretchered off late in the first half to be replaced by Brad Collins with what looked a potentially serious knee injury.
It was a pretty paltry first 19 minutes before Hamer fired the Blades ahead with a beautifully struck free-kick.
Coventry defender Bobby Thomas tried to remove the shirt from Hamer's back as the Brazil-born Dutchman powered forward - and got a booking for his trouble.
But there was further serious punishment when Hamer, who had set up both Blades goals in their 2-2 draw with then managerless City in November, delivered an excellent curling right-foot free-kick from 25 yards.
Dovin did get a hand to it - but it was not a strong enough contact to palm the strike away as the ball found the top right corner.
There was worse to follow for the big away following, however, when United doubled their lead on the half hour.
Femi Seriki squared a pinpoint right-foot pass from just outside the box to pick out Campbell, who stuck out his left foot to instinctively find the bottom left corner. And Campbell was so close to making it 3-0 only to drag wide his low left-footed shot from the edge of the box.
