Inter came from two goals down to win 4-2 on Sunday.
And former Tottenham star Eriksen declared: "It was a fantastic experience. The first half was sad, but winning that way with that comeback was really, really special. Now I can leave the stadium with a huge smile on my lips.
"The fans had prepared a huge choreography, which filled one end of the stadium. That atmosphere is not allowed in the Premier League, partly because they are not allowed to.
"Here you can really feel the fans support one from the minute you arrive on the team bus. They clap their hands on the side of the bus, and you can feel their passion and how important the fight is."
