Frank Lampard scored both goals for Chelsea
Frank Lampard served a timely reminder of his goal-scoring ability as his double carried Chelsea back to third with a hard-earned win over Everton.
The 34-year-old, who is out of contract in the summer, headed in Ramires' cross and stabbed in from close range after his side had conceded in 62 seconds, reports the BBC.
Steven Pienaar gave Everton an early lead, following in after Victor Anichebe nodded against the post.
Nikica Jelavic hit the bar and missed a late chance as the hosts fell short.
Chelsea's fourth successive league win under interim boss Rafael Benitez, after failing to win in his first three, means the Blues finish 2012 four points off Manchester City and 11 off leaders Manchester United, but with a game in hand on both.
Whether Lampard finishes 2013 with the Stamford Bridge club remains in doubt, with the England midfielder free to agree pre-contract terms with a foreign club in January.
For all the promise of Oscar and Eden Hazard and the undoubted ability of Juan Mata, Chelsea's travelling fans made it clear that they believed that it is to soon to consign Lampard, who joined the club 11 and a half years ago, to Chelsea history.
His goals brought to an end Everton's formidable unbeaten run at Goodison, which stretched back 14 previous games to March's 1-0 defeat by Arsenal.
The home team certainly settled into the match like a team at ease in their surroundings, scoring with their first attack.
In the absence of Seamus Coleman and Phil Neville, Phil Jagielka roamed forward from his unaccustomed right-back spot to deliver a cross that Anichebe nodded against the woodwork. Pienaar gleefully dispatched low past Petr Cech.
