The Blues, who are unbeaten in their last three matches, could have dropped out of the topfour by the time they play on Sunday afternoon if other results go against them. Rafael Benitez's side currently hold a one-point lead over fifth-placed Tottenham Hotspur.
Swansea's 0-0 draw with Southampton last week moved the club closer to securing Premier League status for next season. They will be hoping to cement their place in the top half of the table when they travel to West London.
However, the Swans have won just one of their last six matches since clinching the Capital One Cup in February.
Swansea boss Michael Laudrup has no injury concerns ahead of the game so he is likely to name the same starting XI which drew with Southampton.
Possible starting lineups
Chelsea: Cech; Azpilicueta, Ivanovic, Luiz, Bertrand; Ramires, Mikel, Oscar, Mata, Hazard; Ba
Swansea: Vorm, Rangel, Chico, Williams, Davies; Britton, De Guzman, Hernandez, Michu, Dyer; Moore
Sports Mole says: 3-1
