Atletico Madrid have been told by UEFA to empty 'at least 5,000 seats' at the Wanda Metropolitano for Wednesday's second leg of their Champions League quarter-final against Manchester City.
This report comes after several Spanish supporters appeared to give Nazi salutes during their 1-0 first-leg defeat at the Etihad Stadium last week, and one away fan was charged with suspected racist abuse by Greater Manchester Police.
A statement from UEFA read: "The UEFA Appeals Body has announced the following decision which would affect the attendance of supporters to UEFA matches.
"To order the partial closure of the Club Atletico de Madrid stadium during the next (one) UEFA competition match in which Club Atletico de Madrid would play as the host club, for the discriminatory behaviour of its supporters.
"Club Atletico de Madrid shall inform prior to the match, the sector(s) to be closed, which shall at least comprehend 5,000 seats."
The Spanish club has also been forced to display a banner with the phrase '#NoToRacism' and the UEFA emblem on Wednesday night.
This is the second time the La Liga club has been forced to temporarily close its stadium due to suspected discriminatory behavior, following the exhibition of a racist flag during the Europa League final versus Marseille in 2019.
Diego Simeone's team enters the second leg against Manchester City after falling to Mallorca 1-0 in the Spanish top league last weekend, while the Citizens drew 2-2 with Premier League championship rivals Liverpool.
