The 1968–69 season of the European Cupfootball club tournament was won by AC Milan, who beat Ajax 4–1 in the final, giving Milan its first European Cup title since 1963, and its second overall. A number of Eastern Bloc clubs withdrew from the first two rounds when UEFA paired up all of the Eastern Bloc clubs against one another in the aftermath of the Soviet invasion of Czechoslovakia.
Substitutions of two players at any game time were allowed; obligatory match dates were introduced (two weeks between the legs) and fixed on Wednesdays; the away goal rule was extended to the first and second rounds.[1]
This year's competition included only five debutants: Denmark's AB, Cyprus's AEL Limassol, England's Manchester City, Norway's Rosenborg, and Czechoslovakia's Spartak Trnava. This was the smallest number to date.
