Both David Alaba and Casemiro could miss Real Madrid's Champions League semi-final against Manchester City on Tuesday, according to manager Carlo Ancelotti.
Both players have muscular issues, and while they were both named to the travelling team, their availability for the game is in serious doubt.
Ancelotti, on the other hand, will have fullback Ferland Mendy available after returning to full training.
"We have some reservations about Alaba and greater doubts about Casemiro based on what we saw yesterday in training," the Italian remarked during his pre-match press conference.
"Training will provide us with further information. With Alaba, we have greater faith than with Casemiro."
