Juventus forward Cristiano Ronaldo took part in training ahead of Wednesday's Champions League match against Atletico Madid, but manager Maurizio Sarri said he remains a doubt for the match in Turin.
The 34-year-old Portuguese international was rested for Saturday's Serie A game against Atalanta which Juventus won 2-1 thanks to a Gonzalo Higuain double to stay top of the Italian league.
"Cristiano trained with his teammates yesterday [Sunday]," said Sarri.
"It seems that his condition is improving but we still have to evaluate between today and tomorrow.
"The positive thing he was able to play throughout the training session with his teammates."
Defender Matthijs de Ligt, who suffered a dislocated shoulder, and forward Federico Bernardeschi, who bruised his chest, also need to be evaluated, Sarri said.
Juventus can secure top place in Group D with victory over Atletico, with Sarri's side currently on 10 points from four games.
Atletico held Juventus to a 2-2 draw at home in September's corresponding fixture and arrive in Turin trailing the Italian by three points.
