The agent of Michael Folorunsho says he has another level to reach.
The Napoli midfielder is currently on-loan with Hellas Verona.
Agent Mario Giuffredi told Radio Serie A: "For me he arrived in Serie A a few years late. He has the potential of a great team, of Inter, Juve, Milan, Napoli if not the Premier League.
"I believe that within a couple of years he will be able to try his hand at those levels.
"Already in Verona, in a team in difficulty, he is making important performances for his growth path with continuous improvements."
