Real Madrid defender David Alaba did not train with the squad on Monday, casting doubt over his participation against Manchester City.

Alaba, who has added a LaLiga title to his 10 Bundesliga crowns after Madrid sealed their domestic triumph on Saturday, trained inside away from the rest of the squad, according to an update on the club's official website.

The versatile defender, signed on a free transfer last season following the expiration of his Bayern Munich contract, has played a key role in Carlo Ancelotti's defence this term and has made 45 appearances across all competitions, all of them starts.

However, Alaba was taken off in the first leg of the Champions League semi-final against City last week, which finished 4-3 in the Premier League leaders' favour, with a hamstring issue, and it is unclear if he will return in time to play against Pep Guardiola's team in Wednesday's second leg. He did not play against Espanyol on Saturday.

Madrid are vying for a place in the final, which will take place on May 28 in Paris. Liverpool lead Villarreal 2-0 on aggregate in the other semi-final.

Gareth Bale did also not take part in full training, while Eden Hazard continues his recovery from a fibula fracture.
