Rui Vitória has named a 21-man preliminary squad for Saturday's hotly anticipated Clássico. Victor Lindelöf and Eliseu have both shaken off knocks picked up on international duty, but Raúl Jiménez has not been so lucky; the Mexican striker could be out for two to three weeks with a right thigh injury. Luka Jović has taken his place.
Raúl is joined in the treatment room by Jardel, who has sprained his left ankle. The Brazilian's injury presents a rare opportunity to Lisandro López, who returns to the first team squad.
Álex Grimaldo has resumed full training after abdominal surgery, although it is unclear whether he is fit to start this weekend. He replaces Marcelo Hermes. Ljubomir Fejsa and Filipe Augusto have both recovered from their ankle injuries, but André Horta is conspicuous by his absence.
Saturday's game at the Estádio da Luz gets underway at 20:30 local time and will be officiated by Carlos Xistra.
Goalkeepers: Ederson and Júlio César
Defenders: Lisandro, Grimaldo, Luisão, Lindelöf, Eliseu, André Almeida and Nélson Semedo
Midfielders: Fejsa, Filipe Augusto, Samaris, Carrillo, Živković, Salvio, Pizzi, Cervi and Rafa Silva
