Real Madrid manager Carlo Ancelotti has named an ineligible player in his teams travelling squad to face Manchester City on Wednesday.
City hold the home advantage heading into the second-leg of the quarter-final Champions League tie with the aggregate score level at 3-3 after a thrilling previous encounter in the Spanish capital.
Ancelotti is determined to have every one of his top stars join the team for the trip to England and has included a midfielder suspended for the game in Madrid's 22-man squad.
Several Madrid players were riding their luck on yellow cards prior to City's trip to the Santiago Bernabeu and Aurelien Tchouameni's booking means he is unable to participate against City.
His booking against Pep Guardiola's side was the Frenchman's third in the competition this season and means he can play no part in the Etihad fixture.

Tchouameni was not expected to travel with Madrid to England but has been picked by Ancelotti despite his unavailable status.
The 24-year-old is expected to train alongside the rest of his team-mates in preparation but can play no part in the knockout clash as Madrid attempt to progress to the semi-finals.
Either Nacho Fernandez or Eder Militao are expected to fill in for Tchouameni who has been a key feature in Madrid's midfield this season with 34 appearances in all competitions.

The decision to include him in the squad throws up memories of a mistake Madrid previously made in 2015 when the club were expelled from the Copa del Rey for fielding an ineligible player.
Denis Cheryshev was serving a one-match ban when Madrid played Cadiz and scored in the match despite being hit with a one-game suspension before the game.
Speaking after the game, Ancelotti looked ahead to facing City, stating: 'We are not going to win the game [vs Manchester City] through fitness, but through attitude. City are physically very strong.'
