Zanetti wrote an open letter to Inter fans on Monday:
“The closer it came to May 2010, the more we felt like Formula 1 drivers: we couldn't get a single corner wrong.
“We were always playing, training was a chance to keep our focus high. I could always sleep the nights before games, others, like Cambiasso, had much more difficulty sleeping.
“I have so many snapshot memories of that game in Madrid that light up my face, a bit like when I raised the trophy itself.
“When we came out to warm up and I saw the Inter fans, I could hardly believe it: there wasn't an empty seat in the house.
“I said to myself: they're here for us, we can't let them down. They showed me pictures of Milan in the post-match interview.
“The Piazza del Duomo was full, the people filled the streets and were going crazy with joy. It moved me, because I realised that my happiness, the happiness of all of my teammates, was second to the joy of our Nerazzurri people.
“Have you ever seen a stadium open and full of people at dawn? I think that San Siro was the most extraordinary example in history.
“I've always admired the resilience of Nerazzurri fans, their ability to be close to you as a player.
“The empathy, ever since I arrived, was just natural. Inter fans are special: always there, pushing you, with a depth of feeling which is well out of the ordinary."
