If Liverpool had any nerves, they coped in song - and as a consequence shattered the composure of their Italian opponents.
BBC Sport's Mark Lawrenson played in that final, which Liverpool won on penalties after the game ended 1-1 over 90 minutes, and remembers the incident all too well.
He said: "We had a lot of laughs in our dressing room and some big personalities. We'd already had a walk around the pitch to take in a very hostile atmosphere, which was Graeme Souness's idea, then we were walked out into the tunnel for kick-off.
"We had a lad in our squad called David Hodgson, who was from Middlesbrough. The singer Chris Rea also came from Middlesbrough and Hodgy started singing his song 'I Don't Know What It Is But I Love It'.
"We all started singing it. Roma's coach Nils Liedholm was finishing his team talk when he heard all this and he said afterwards he saw the colour draining out of his players' faces to hear the opposition all giving a song moments before a game like that. It relaxed us and made them nervous
