Chelsea v Arsenal: Premier League – live
Arsenal #Arsenal
Pierre-Emerick Aubameyang starts against his old club. That’s one of four changes from Chelsea’s last league game, the 4-1 defeat at Brighton. Edouard Mendy, Jorginho and Cesar Azpilicueta also come into the side; Kepa Arrizabalaga Mateo Kovacic, Conor Gallagher and Christian Pulisic drop out.
The Chelsea Twitter feed suggests they are playing a back three, with Mason Mount in central midfield alongside Jorginho. I’m calling fake news: it looks like a back four to my admittedly untrained eye.
Mikel Arteta makes one change to Arsenal’s recent Premier League XI – Oleksandr Zinchenko replaces the injured Takehiro Tomiyasu at left-back.
Chelsea (possible 4-2-3-1) Mendy; Azpilicueta, Chalobah, Thiago, Cucurella; Loftus-Cheek, Jorginho; Sterling, Havertz, Mount; Aubameyang.
Substitutes: Bettinelli, Koulibaly, Gallagher, Hall, Kovacic, Zakaria, Pulisic, Ziyech, Broja.
Arsenal (4-1-4-1) Ramsdale; White, Saliba, Gabriel, Zinchenko; Partey; Saka, Odegaard, Xhaka, Martinelli; Jesus.
Substitutes: Turner, Tierney, Holding, Cedric, Lokonga, Elneny, Vieira, Nelson, Nketiah.
Referee Michael Oliver.
