Atletico Madrid have been ordered to close part of their stadium for their Champions League return clash with Manchester City after fans performed Nazi salutes at the first leg.
The Spanish side will have to ensure at least 5,000 seats – in home areas – are not filled for Wednesday's quarter-final decider against Pep Guardiola's side at the 68,456-capacity Wanda Metropolitano.
Video footage captured travelling supporters making the sickening gesture at the Etihad Stadium during City's 1-0 victory last Tuesday.
UEFA launched an investigation after the game and their appeals body on Monday announced the penalty.
They have told the club that they will face a 'partial closure' for 'the discriminatory behaviour of its supporters'. Officials will have to notify UEFA ahead of the match the section or sections which will be closed, with no fewer than 5,000 seats left empty.
Atletico have also been ordered to display a banner with the wording '#NoToRacism' and the UEFA logo on it.
Around 2,100 Atletico supporters were in Manchester for the tie. Some were accused of spitting at City supporters and there were also reports of a steward being assaulted.
