Diego Costa has given Atletico Madrid fresh hope he could face Real Madrid after taking part in training ahead of Saturday's Champions League final.
The striker was considered a major fitness doubt after limping out of last weekend's title-clinching 1-1 draw at Barcelona, but he was able to complete a number of drills at Estadio da Luz.
Costa has been struggling with a minor hamstring injury and it remains to be seen whether Atletico will take a risk on the 25-year-old, who is expected to join Chelsea later in the summer.
Reports suggest the Spain international has turned to horse placenta treatment in a desperate bid to be fit, but Sky Sports' Guillem Balague questioned whether he can recover in time.
He said: "This was controlled movement, no-one is testing themselves really.
"I'm pretty sure that Diego Costa's been asked not to stretch himself because he will be given all the time he needs, until the last minute of the game before they actually decide what they are going to do with him.
"It will be touch and go.
"It wasn't a proper tear they say, which looks like perhaps he will make it, but nature is nature and it will almost be like a miracle."
Midfielder Arda Turan, who has been nursing a pelvic problem, was also able to take part in the light session at the stadium in Lisbon, which hosts the final.
