The talented winger came through the ranks at Fiorentina and made 93 appearances for the first-team.
His talents were scouted by league rivals Juventus and a €40m transfer was eventually agreed upon in July 2017.
But despite his obvious potential, the 26-year-old hasn't delivered on a regular basis with just 10 goals in 108 appearances for Juve.
A player who could be coming the other way to Italy is Lionel Messi.
Quizzed on the possibility of Messi joining Serie A, Amoroso added: "It seems strange to me, but after Ronaldo never say never."
Lautaro Martinez has been linked with a move to Barca, but Amoroso says he "hopes he stays" at Inter.
