It's amazing that Inter lost yesterday, but for Italian football as a whole, Inter's defeat marked a full decade - exactly 10 years - without any European trophy for an Italian club.
This is the longest wait ever for Italian teams. The negative record was already set 3 years ago, because the previous record without European trophy for Italians was 6 years (no trophy in 1978, 79, 80, 81, 82, 83). But in those particular trophyless years, the Italian NT won the world cup in 1982. This time, not only the Italian teams, but the Italian NT was living through it's darkest ages, especially at the World Cups.
It's safe to say that this was the worst decade in the history for calcio. Some might say that 4 finals (Juve twice in CL, Inter in EL and Italy at EURO 2012) aren't bad, but we are talking about a league and a NT that were regularly winning 5, 7, 10, and once, from 1991-2000, 13 European trophies in a decade. This time, big zero.
