Real Madrid could be without Casemiro and David Alaba for their Champions League tie with Manchester City on Tuesday evening.
The LaLiga giants will face Manchester City at the Etihad stadium after overcoming Chelsea to reach the semi-final of the Champions League.
Casemiro and Alaba will travel to England for the fixture but a decision regarding their fitness will be made in the final hour as they are said to be struggling with injuries.
According to Marca, the pair struggled to finish a squad training session at Valdebebas.
The details of their injuries have not yet been disclosed and Real Madrid are said to be making a 'late fitness' call ahead of their clash with City.
However, Madrid have been handed as boost as Ferland Mendy is said to be available for Tuesday evening's fixture.
Mendy completed a full training, without any issues, ahead of their trip to the Premier League giants. Therefore, he will be in contention to start the game at the Etihad.
Alaba recently suffered a hamstring issue - having to be taken off during Real Madrid's 3-1 win at Osasuna.
The Austrian scored the opening goal in Madrid's 3-1 win - which has left Carlo Ancelotti's side needing just four more points to clinch the LaLiga title.
However, he went down clutching his hamstring after Marco Asensio scored Real Madrid's second goal on the stroke of half-time.
He continued until half-time, but did not reappear for the second-half with Dani Carvajal replacing him in the back-line.
Alaba has been a key part of the Madrid defence this season and any absence would be a significant blow as the season reaches its finale.
Alaba has been instrumental in the heart of Real Madrid's defence this season and his absence from their clash against Manchester City on Tuesday would be devastating.
Meanwhile, Casemiro has not featured for Real Madrid since their second-leg quarter-final match against Chelsea.
Therefore, Eduardo Camavinga could replace Casemiro in the starting lineup, while Nacho could feature alongside Eder Militao if Alaba is ruled out of the fixture.
