Serie A clubs weren't afraid to spend money to ensure their league had the game's biggest stars, with Roberto Baggio, Ronaldo and Zinedine Zidane all playing there at some stage.
But 1990 was a particularly good year, with Milan, Sampdoria and Juventus winning the three European trophies on offer.
European Cup final: 23 May, 1990
Milan beat Benfica 1-0 thanks to a Frank Rijkaard goal to claim back-to-back successes after their 4-0 thrashing of Steaua Bucharest.
They won it again in 1994, but lost to Ajax in the final the following the year.
Roberto Galia, Pierluigi Casiraghi and Luigi de Agostini helped Juventus beat Serie A rivals Fiorentina 3-1 in a two-legged final and add to La Viola fans' hatred of Juve.
Napoli had won the 1989 edition, while six other Italian clubs had won the UEFA Cup by 2000 where there were three other all-Italy finals.
Sampdoria beat Anderlecht 2-0 thanks to extra-time goals from Gianluca Vialli.
Sampdoria actually prevented a clean sweep from Italian sides in 1989 when they were beaten in the same final by Barcelona.
This tournament was stopped in 1999 with Serie A side Lazio winning the last ever final, while Parma contested successive finals in 1993 and 1994, losing to Arsenal in the latter.
