Both Liverpool and Borussia Dortmund were appearing in their first European final. It was Liverpool's second season in European competition, the previous season they had been eliminated in the semi-finals of the 1964–65 European Cup by Internazionale. Dortmund first competed in European competition in the 1956–57 European Cup, when they were eliminated in the second round. Their best performance in Europe to date was in the 1963–64 European Cup. Like Liverpool they were eliminated in the semi-finals by Internazionale.

Liverpool had won the 1965–66 Football League, a victory over Chelsea ensured they became English champions. Their league success meant that whatever the result they would be competing in the European Cup the following season. Borussia Dortmund had finished as runners-up in the 1965–66 Fußball-Bundesliga, three points behind champions 1860 Munich. As Bayern Munich had won the 1965–66 DFB-Pokal, Dortmund's only chance of participating in European football the following season was to win the Cup Winners' Cup.

The weather in Glasgow was stormy, with torrential rain nearly flooding Hampden Park. As a result, the stadium did not reach its normal capacity of 100,000, with 41,657 spectators attending the match. The first half was mostly uneventful as both teams negated the threat of the other. Despite this both sides had opportunities to take the lead. At the start of the match, Liverpool striker Ian St John had a shot cleared off the goal line and midway through the second half Dortmund defender Theodor Redder almost scored an own goal. Towards the end of the half, Dortmund began to have more of an attacking threat. They were only denied by a number of saves from Liverpool goalkeeper Tommy Lawrence, ensuring it remained 0–0 at half-time.

Liverpool had the majority of the possession up to this point, with Dortmund content to counter-attack. The tactic worked as Dortmund took lead in the 61st minute. Sigfried Held passed to Lothar Emmerich on the left hand side of the pitch, Emmerich played a lofted pass to Held, who volleyed the ball into the goal to give Dortmund a 1–0 lead. Seven minutes later Liverpool were level. Peter Thompson ran down the left hand side of the pitch and passed to Roger Hunt who scored to level the match at 1–1. The linesman on the left-hand side of the pitch signalled to the referee that the ball had gone out of play, yet the referee ignored him and allowed the goal to stand. There were few chances for either side until the end of the half when Liverpool had a chance to win the match, but Hunt's shot missed. With the scores still level at 1–1, the match went into extra-time.

The winning goal came in the 107th minute. A clearance by Liverpool goalkeeper Lawrence found Dortmund midfielder Reinhard Libuda. Libuda shot 35 yards from goal on the right hand side of the pitch. The shot went over Lawrence and Liverpool defender Ron Yeats hit the post and rebounded off Yeats into the Liverpool goal to give Dortmund a 2–1 lead. The score remained the same throughout the remainder of extra-time and Dortmund became the first German team to win the Cup Winners' Cup.
