There was a certain amount of prestige that went with the competition at one point and clubs have had some of their greatest nights as a result.
Retro Football Blog will be looking at when the Cup Winners Cup was a thing and some of the great matches which have taken place.
To refresh your memory, though...
Teams involved included the previous season’s domestic cup winners. If they had also won the league, however, then that side would compete in the European Cup instead and the runners-up of the FA Cup, Coppa Italia etc, would take their place.
Fiorentina won the inaugural tournament when they beat Rangers in a two-legged final in 1961 and the following year on 10 May, the Italians reached the final again where a 1-1 draw with Atletico Madrid forced a replay.
Fans had to wait FOUR months for that replay to happen due to the 1962 World Cup in Chile which began at the end of May with a number of players being summoned for international duty.
The game finally took place on 5 September in Stuttgart and Atletico won 3-0.
That 1961/62 campaign saw UEFA take charge of the competition’s organisation for the first time and there was an increase of entrants, up from 10 in the 1960/61 season to 23.
And for 40 years clubs competed until the tournament was absorbed by the UEFA Cup, as the growing success of the Champions League reduced the need for three European competitions.
Lazio won the last ever game when they beat Mallorca at Villa Park in 1999.
Barcelona are the only club to win the tournament on four occasions – 1979, ‘82, ‘89 and ‘97
