Casemiro and David Alaba trained with the rest of their team-mates on Monday, raising doubts about whether or not they will be in the starting eleven. Ancelotti will make the decision at the last minute.
Casemiro, Real Madrid's biggest doubt ahead of the clash with Manchester City, trained alongside the rest of his teammates at the Etihad Stadium.
The Brazilian took part in the session, which was open to the media for 15 minutes, alongside David Alaba, who is also injured for the clash.
Carlo Ancelotti told a press conference that Casemiro is in trouble to start on Tuesday and said there were many doubts about the Brazilian. The Italian coach reported that Ferland Mendy is now recovered and that he has doubts about Alaba.
"Training will tell us more. Casemiro is trying, he's close, if he's not going to play in this game he'll play in the next one," Ancelotti told the press conference.
The Madrid players, well wrapped up in warm clothes due to the cold weather in Manchester, began the session with a technical talk from Ancelotti, before a short warm-up without the ball.
