Liverpool's history will remain forever scarred by the Heysel tragedy.
This tragedy put an end to a decade of English domination on the continental scene, having won seven times in eight years, including four for Liverpool (1977, 1978, 1981 and 1984). English clubs were banned from all European competitions indefinitely. This suspension lasted five years, six for Liverpool.
The two sides had to wait until the 5th of April 2005, twenty years after the tragedy, before facing each other again, in the quarter final of the Champions League. Before kick-off, a display of the word "Amicizia" ("Friendship") was unfurled at the KOP of Anfield.
