Atletico Madrid forward Diego Costa has trained with his teammates ahead of the club's meeting with Liverpool at Wanda Metropolitano on Tuesday.
The Reds return to the ground for the first time since winning the Champions League trophy in May and could have to face a fit-again Costa.
According to Sky Sports News, the former Chelsea player could be fit enough to play a part on Tuesday after recovering from surgery for a slipped disk in his back.
Costa last played for Atletico in November against Espanyol, with Alvaro Morata starting the majority of games in his absence.
The 31-year-old has scored 14 goals in 59 appearances since he returned to the club in 2018.
The report adds that Joao Felix and Kieran Trippier are set to miss out on Tuesday's match due to injury.
