Chelsea, playing with a swagger missing for much of the season, routed Aston Villa 8-0 as English Premier League leaders Manchester United wasted the chance to move six points clear after a 1-1 draw at Swansea City.
Chelsea striker Fernando Torres began the goal glut after three minutes at Stamford Bridge and David Luiz and Branislav Ivanovic made it 3-0 at the break.
Frank Lampard marked his 500th Premier League game and first league start since October with a rasping fourth before Ramires (two), Oscar and Eden Hazard joined the fun as Chelsea secured a first home league win under interim manager Rafael Benitez.
It took Chelsea's goal tally to 13 in two games after they thrashed Championship (second division) side Leeds United 5-1 to reach the League Cup semi-finals in midweek.
The overnight (NZ time) victory matched Chelsea's 8-0 demolition of Wigan Athletic at home in 2010. The record Premier League winning margin is Manchester United's 9-0 defeat of Ipswich Town in 1995.
United led at Swansea through Patrice Evra after 16 minutes but the league's top scorer Michu netted his 13th goal of the campaign for the hosts, moving the Spaniard one ahead of Robin Van Persie, to level just before the half-hour.
United, who hit the woodwork twice in the second half through Van Persie and Michael Carrick, hold a four-point advantage over Manchester City, who beat Reading 1-0 on Saturday, heading into a busy holiday programme.
The leaders have 43 points from 18 games, followed by City on 39. Chelsea moved back up to third place with 32.
United manager Alex Ferguson was hardly in festive mood after his side's trip to Wales, rueing two points that got away, claiming Van Persie "could have been killed" by Swansea captain Ashley Williams and criticising referee Michael Oliver.
"We absolutely battered them and we are very unlucky," Ferguson told Sky Sports. "It should have been a six-point gap (over City) today and that is the disappointment."
Ferguson was incensed when a prone Van Persie was struck in the head from point-blank range by a clearance from Williams with the whistle having been blown for a foul on the Dutchman.
The Scot said it was a "deliberate act" and called for Williams, booked along with Van Persie, who escaped injury, in the melee that followed, to receive a long ban.
"Robin van Persie is lucky to be alive. It was a disgraceful act from their player today and he should be banned by the FA. Robin could have had a broken neck," said a seething Ferguson.
Swansea welcomed back Michel Vorm after the goalkeeper missed 10 games with a groin injury and the Dutchman was soon called into action to beat away a Wayne Rooney drive before he quickly followed up to deny Ashley Young.
However, from the resulting corner Evra met Van Persie's delivery with a glancing header that eluded Leon Britton who was stationed on the goal-line.
United have scored 10 goals from corners in the Premier League this season, more than any other side.
