The team is the one selected a week ago for the win at home to Newcastle.
That means Eden Hazard with Willian and Pedro either side of him continue as the front three. Willian is searching for the goal that will take him onto the 50-mark for the Blues.
Jorginho is joined by N'Golo Kante and Mateo Kovacic in midfield, and the defence is one selected for the previous seven Premier League games, with Toni Rudiger and David Luiz flanked by skipper Cesar Azpilicueta on the right and Marcos Alonso on the left. It is Rudiger's 50th Premier League game. Kepa Arrizabalaga continues in goal.
Arsenal bring Hector Bellerin, Lucas Torreira and Aaron Ramsey into their side. Mesut Ozil is named among their subs. Alexandre Lacazette and Pierre-Emerick Aubameyang both start in the Gunners’ attack.
Chelsea: Kepa; Azpilicueta (c), Rudiger, David Luiz, Alonso; Kante, Jorginho, Kovacic; Pedro, Hazard, Willian.
Subs: Caballero, Christensen, Emerson, Ampadu, Barkley, Hudson-Odoi, Giroud.
Arsenal: Leno; Bellerin, Sokratis, Koscielny (c), Kolasinac, Torreira, Xhaka, Guendouzi, Ramsey, Aubameyang, Lacazette.

Maurizio Sarri’s side have the third best away record in the Premier League this season, with 22 points from a possible 30. Only Tottenham (30) and Liverpool (29), who have both played two more, have accumulated more points over the same period.
The Blues have conceded a total of just four goals in their last seven league games.
Chelsea have scored 13 goals in the final 15 minutes of matches this season – more than any other Premier League side.
Chelsea are looking to win four consecutive Premier League away games for the first time since September 2017 (a run that ended on five).
Five players – Kepa Arrizabalaga, Cesar Azpilicueta, Antonio Rüdiger, Marcos Alonso and N’Golo Kanté – have started every Premier League game this season.
