Savona joined Forest in August from Juventus and already has two goals.
"Is the Premier League different inside? It's even more beautiful," he told La Gazzetta dello Sport.
"There's a completely different style than in Italy and a special, unique atmosphere. In England, there's less tactics and more intensity, it's a constant back and forth: anything can happen at any moment.
"Serie A remains a difficult and important championship, a great tournament: last season was crucial for my growth."
Savona added lm Juve: "For me, it will always be home. Right now, however, I'm focused on Nottingham Forest, where I'm having a wonderful experience: I get along well with my teammates, in the city, and I really like the English atmosphere."
