Chelsea will sit third in the Premier League at Christmas after smashing sorry Aston Villa for eight unanswered goals in a farcically one-sided encounter at Stamford Bridge.
Fernando Torres' power header got the ball rolling for Rafael Benitez's men inside three minutes before a stunning free-kick by David Luiz and a Branislav Ivanovic header had the points in the bag by the break.
Villa goalkeeper Brad Guzan did his best to limit the damage with a string of fine saves in the second half, but he could not keep out Frank Lampard's stinging long-range effort and then suffered the ignominy of Ramires slotting a fifth between his legs.
Oscar made it six from the spot in the 79th minute and there was still time for Eden Hazard to become the seventh different goalscorer when he lashed home, while Ramires made it eight at the death as Paul Lambert's men were brought back to earth with a bump following last week's impressive win at Liverpool.
After Benitez's reign began in low-key fashion with goalless stalemates against Manchester City and Fulham, the European champions have since averaged more than three goals a game after netting 26 times in seven matches in all competitions. Chelsea's performance also marked the first time seven different players had scored for the same team in a single Premier League match.
Bouncing back from Japan
The Blues shrugged off the disappointment of losing the FIFA Club World Cup final to Corinthians a week ago with a 5-1 drubbing of Leeds in the Capital One Cup in midweek, and they started with their tails up today and soon took the lead through Torres.
Cesar Azpilicueta created the opportunity, his cross from the right finding his fellow Spaniard who still had much to do from 16 yards, but generated enough power on his header to beat Guzan. The threat of Villa's Christian Benteke was much discussed ahead of the match after his two goals and superb assist for Andreas Weimann in the win over Liverpool, and the Belgium international was the focal point in the visitors' search for an equaliser.
Yet it was the hosts who continued to control proceedings and, with 29 minutes gone, they added a sublime second through Luiz, who was again revelling in the midfield role he first graduated to at the Club World Cup. Hazard led a swift counter-attack to win a free-kick on the edge of the box, and Luiz produced a free-kick to rival Cristiano Ronaldo at his best as he thumped in an arrow-straight effort with his instep that dipped wickedly over the wall and beyond Guzan.
The home fans were celebrating again in the 34th minute when Gary Cahill's deflected shot drew a parry from Guzan but Ivanovic was on hand to head the rebound high into the net. Villa emerged for the second half in damage-limitation mode, but they had a let-off within five minutes as Guzan tipped a rasping Mata drive over the bar.
Benteke relieved the pressure by winning a corner after a run and shot from deep, but Chelsea had no problem clearing their lines and might even have scored on the counter-attack but Ashley Cole blazed over. Guzan denied Torres a second with another fantastic reaction save in the 56th minute, while the Villa goalkeeper also denied Moses in a one-on-one situations seconds later.
Subs make their mark
But the American was helpless to prevent Lampard adding a fourth in the 58th minute, the England midfielder marking his return to the starting XI with a wonderful low strike from 25 yards, becoming Chelsea's all-time leading league goalscorer in the process. Lampard was withdrawn on the hour to be replaced by Ramires, and five minutes later Chelsea goalkeeper Petr Cech was finally called into meaningful action as he deflected Weimann's low shot onto the crossbar.
Oscar was brought on as Benitez opted to rest Torres ahead of the busy festive programme, and the Brazilian should have marked his arrival with a goal in the 68th minute but screwed his shot wide. Lucas Piazon entered the fray to make his Premier League debut as Mata's replacement in the 74th minute, and within seconds the 18-year-old had his first top-flight assist as his perfectly-weighted pass found Ramires who slotted under Guzan.
In the 79th minute Oscar was bundled over in the area by Chris Herd and the Blues midfielder picked himself up to plant his penalty beyond a dispirited Guzan. Four minutes later it was seven as Hazard received the ball in the area and turned smartly away from his marker before burying the ball high into the left corner of the net.
It might have been eight in the final minute after Piazon won a penalty after a foul by Clark, but the debutant could not add to Villa's misery as Guzan guessed right to make a good save. Yet there was still time for Villa to suffer further humiliation as Ramires turned home Oscar's pass beyond a clearly fed up Guzan, who could only wearily pat the ball into the back of the net.
