Both teams have picked up the maximum nine points from their opening three games and are already starting to see a return on their summer acquisitions.
Gylfi Sigurdsson has scored one goal and provided three assists since making a £10m switch back to Wales, but it is Chelsea who have done arguably the best business.
The striker has scored four goals in his first three games since his £32m arrival from Atletico Madrid, including two in the thrilling 6-3 victory over Everton before the international break.
Chelsea are optimistic on the Belgian's fitness, but have plenty of alternative options in a squad so deep with quality that they have already been made the favourites to win the title this campaign.
Filipe Luis and Oscar, who was not even among the substitutes last time out, may have to be content with places on the bench, but the Brazilian duo, plus compatriot Ramires, will likely get their starting chance when Chelsea begin their Champions League campaign against Schalke on Wednesday.
The Swans had a taste of European football themselves last year and seem to be benefitting from the absence of early-season continental fixtures.
They have eight more points than at this stage last term, and Garry Monk has been able to name the same side for all of their Premier League outings.
Considering their 3-0 triumph over West Bromwich Albion a fortnight ago, there is no reason that the youngest manager in the division will change things dramatically for their trip to the capital.
Liberty Stadium new boys Tom Carroll and Jefferson Montero are also yet to start in the top flight, with the form of Ki Sung-yeung and Nathan Dyer, who has three goals already, limiting them to the bench thus far.
Chelsea have kept clean sheets in eight of their last nine top-flight home games and have not lost in the league to Swansea since 1981.
Possible starting lineups
Chelsea: Courtois; Ivanovic, Cahill, Terry, Azpilicueta; Matic, Fabregas; Hazard, Willian, Schurrle; Costa
Swansea: Fabianski; Rangel, Williams, Amat, Taylor; Shelvey, Ki; Dyer, Sigurdsson, Routledge, Gomis
Sports Mole says: 1-0
