Chelsea have the chance to get revenge on Everton - who beat them 1-0 at Goodison Park in September - when the sides lock horns on BT Sport this Saturday.
Jose Mourinho's Blues can extend their lead at the Barclays Premier League summit with three points in the lunchtime kick-off, ahead of the weekend's other games.
Chelsea - on 57 points from 26 games - are currently one point clear of London rivals Arsenal, and three ahead of Manchester City, who have a game in hand.
However, sixth-place Everton are no pushovers, and need points to propel themselves back into the race for a European place.
Roberto Martinez's Toffees have claimed just four points from the last 12 available, to fall five points behind fifth-place Tottenham Hotspur.
However, they have a game in hand on Spurs, having seen last week's fixture against Crystal Palace fall victim to the weather.
Despite losing away at Everton earlier in the season, Chelsea will fancy their chances in this one.
The Blues are unbeaten in their last 18 games against the Toffees at Stamford Bridge, having won nine and drawn nine in a sequence stretching back to the 1994-95 season.
Chelsea are also on the longest undefeated run in the Barclays Premier League at present - 11 games - with their most recent loss coming on December 7th in a 3-2 reverse at Stoke City.
BT Sport viewers can tune in to Chelsea v Everton at 12:45pm on BT Sport 1.
Football fans have a number of other games to look forward to on BT Sport this weekend, including a Scottish Premiership clash between Dundee United and Motherwell at 7:45pm on Friday February 21st.
Third-place 'Well can put further distance between themselves and the fourth-place Tangerines, as they look to secure a European spot for 2014-15.
But the last time the sides met, in November, Motherwell suffered a 4-0 thumping on home soil, with 17-year-old Ryan Gauld scoring twice for Dundee United.
This came after the sides played out a 2-2 draw at Tannadice in September.
