Antonio Conte's charges claimed a crucial 4-2 win against Southampton on Tuesday night, but Tottenham Hotspur - Chelsea's sole remaining rivals in the race for the title - responded with a nervy 1-0 win against Crystal Palace on Wednesday night and, so, the Blues have a four point lead at the top of the table with five matches remaining.
Chelsea are chalked up as Betfair Sportsbook's 11/10 (2.10) favourites to move closer to being crowned as champions by taking maximum points from the match in Merseyside, but Ronald Koeman's Toffees will certainly provide stiff opposition.
Everton have lost just one of their last 20 Premier League matches at Goodison Park - a sickening 1-0 defeat against rivals Liverpool, with Sadio Mane scoring in the dying stages for the Reds - while the Toffees have won each of their last eight league fixtures on home turf.
The hosts can be backed at 13/5 (3.60) with Betfair Sportsbook to further extend that proud record by beating the Blues, while the odds compilers offer 5/2 (3.50) that these two teams are forced to settle for a share of the spoils from Sunday's showdown.
Former Chelsea players Oriol Romeu and Ryan Bertrand were on target for Southampton against Conte's men in west London on Tuesday and it is another ex-Chelsea star - Romelu Lukaku - who will lead the line for Koeman's men on Merseyside.
The big Belgian has been outstanding for the Toffees this term, scoring 24 Premier League goals, including 11 in his last six games at Goodison Park; the 23-year-old will certainly be licking his lips at the prospect of facing his former employers, for Chelsea have conceded in each of their last 11 Premier League matches, leaking twice in each of their last three outings in all competitions.
Lukaku can be backed at 17/10 (2.70) to exploit any weakness in Chelsea's defensive unit and add to his impressive tally for the season so far, while 5/1 (6.0) is available that the Belgian breaks the deadlock on Merseyside.
Diego Costa marked his return to scoring form with two goals against Southampton and the Spanish international can be backed at 21/20 (2.05) to find the net against the Toffees, while in-form midfielder Eden Hazard, who has scored 15 Premier League goals so far this season - his best ever tally in the top flight - is available at 6/4 (2.50) with Betfair Sportsbook to score at any time.
There is plenty of potential for the goals to flow in this game; Everton have notched 29 goals in their last eight Premier League games on home soil, while confidence will be coursing through Chelsea's veins, for the Blues have bagged eight goals in their last two outings.
Betfair Sportsbook's 2/1 (3.0) quote, therefore, for this match to produce more than three goals could offer punters a solid selection ahead of Sunday's crucial clash.
