Thomas Tuchel has made five changes to his team to face West Ham United, including a debut for new signing Wesley Fofana.
Fofana joined Chelsea from Leicester City and gets his first game for the Blues from the start as we host West Ham at Stamford Bridge today.
He looks set to line up in defence alongside Kalidou Koulibaly and Thiago Silva, who captains the side, ahead of goalkeeper Edouard Mendy.
Reece James returns after missing our match against Southampton through illness, replacing Cesar Azpilicueta on the right, while Marc Cucurella continues on the left.
In midfield, Mateo Kovacic makes his first start of the season after recovering from a knee injury and Conor Gallagher returns from suspension, plus Ruben Loftus-Cheek starts as the hamstring injury he picked up against Southampton turned out not to be as serious as first feared.
Christian Pulisic comes into the attack with Raheem Sterling, meaning Mason Mount, Kai Havertz, Hakim Ziyech and Jorginho miss out.
West Ham make two changes to the team which drew with Tottenham in midweek. Emerson Palmieri, who joined the Hammers from Chelsea this summer, replaces Aaron Cresswell at left-back after the latter picked up an injury against Spurs.
Elsewhere, another new arrival Lucas Paqueta comes in for Said Benrahma to make his first start for West Ham.
