Diego Costa has not been included in Chelsea’s squad for the Champions League group stages.
The striker has been in a stand-off with Chelsea throughout the summer, having claimed Antonio Conte told him he is not part of his plans at Stamford Bridge and refusing to return from his native Brazil to resume training at the club.
Atletico are banned from registering new players before January and were reluctant to pay Costa’s £150,000 a week wages before he can play for them.
New £70m striker Alvaro Morata is included in Chelsea’s Champions League squad, alongside summer signings Danny Drinkwater, Davide Zappacosta, Antonio Rudiger, Willy Caballero and Tiemoue Bakayoko.
Full Chelsea squad:
Goalkeepers: Thibaut Courtois, Willy Caballero, Eduardo
Defenders: Davide Zappacosta, Victor Moses, Cesar Azpilicueta, David Luiz, Jake Clarke-Salter, Antonio Rudiger, Andreas Christensen, Gary Cahill, Marcos Alonso, Kenedy.
Midfielders: N’Golo Kante, Kyle Scott, Tiemoue Bakayoko, Cesc Fabregas, Danny Drinkwater. Charly Musonda, Pedro, Willian, Eden Hazard.
Forwards: Michy Batshuayi, Alvaro Morata
