Manchester United could be without Anthony Martial, Harry Maguire and Antony for their Europa League second-leg play-off tie against Barcelona.
The Premier League side hosts the reverse fixture with the tie balanced at 2-2 after the first leg at Camp Nou.
United must beat Barca on Thursday to progress to the last-16 of the competition.
However, Martial, Maguire and Antony all missed training ahead of the game.
Martial and Antony had both started light, individual training last week but they are yet to reintegrate into first-team training.
Casemiro is available for the match. Marcel Sabitzer and Lisandro Martinez both missed the first leg through suspension but are available again for selection.
Raphael Varane is also expected to return to their starting line-up, having remained on the bench for Sunday’s win against the Foxes.
