Messi, 31, has earned a legendary status at the Camp Nou and has often stated his desire to end his career at the LaLiga champions.
But in the wake of the Serie A exposure over the last couple of months thanks to the arrival of Cristiano Ronaldo, Saviola feels there's reason to believe for Inter supporters.
The Portuguese star is dragging attraction in the Italian league after many years spent in the shadow of the Premier League and La Liga.
"Leo is really identified with Barcelona, it’s hard to imagine him with another camiseta," he told FCInterNews.
"In the future, however, anything can happen that's why Inter fans can't lose their faith.
"But I repeat, it will be complicated to see Messi join another club."
