In 1985, 39 Juventus fans died in the Heysel stadium just before the start of the European Cup Final. After some debate, organizers decided to celebrate the game anyway. The players, unaware of the disaster, playd the final while the corpses were still visible in the stands
“The Heysel Stadium disaster (French: Drame du Heysel, Dutch: Heizeldrama) occurred on 29 May 1985 when escaping fans were pressed against a wall in the Heysel Stadium in Brussels, Belgium, before the start of the 1985 European Cup Final between Juventus of Italy and Liverpool of England. Thirty-nine Juventus fans died and 600 were injured.
Approximately one hour before the Juventus-Liverpool final was due to kick off, a large group of Liverpool fans breached a fence separating them from a “”neutral area”” which contained Juventus fans. The Juventus fans ran back on the terraces and away from the threat into a concrete retaining wall. Fans already seated near the wall were crushed; eventually the wall collapsed. Many people climbed over to safety, but many others died or were badly injured. The game was played despite the disaster in order to prevent further violence.
The tragedy resulted in all English football clubs being placed under an indefinite ban by UEFA from all European competitions (lifted in 1990–91), with Liverpool being excluded for an additional year and fourteen Liverpool fans found guilty of involuntary manslaughter and each sentenced to three years’ imprisonment. The disaster was later described as “”the darkest hour in the history of the UEFA competitions”” ”
