The 29-year-old retains his spot in midfield from the FA Cup win over Wolverhampton Wanderers last week, meaning that Nemanja Matic must make do with a place on the bench.
Swansea, meanwhile, make just one change from the side that beat Leicester City in what proved to be Claudio Ranieri's final league game in charge of the champions as Wayne Routledge replaces Nathan Dyer, who is sidelined with an Achilles injury.
That means another start for Alfie Mawson, who has three goals in six league games so far in 2017, while Gylfi Sigurdsson will be hoping to add to the 16 Premier League goals he has already directly contributed to this season.
Chelsea are looking for a 12th consecutive home win in all competitions, but Swansea have picked up more points than the league leaders so far in 2017.
