Inter Milan defender Danilo D'Ambrosio has hailed the impact of Nicolo Barella.
Barella proved Italy's matchwinner in victory over Nations League qualifying opponents Holland.
"Nico is a certainty at Inter, I've been training with him for two years now and I know the potential he has," said D'Ambrosio.
"He is a player who knows how to manage all the moments in a match."
Roberto Mancini's Italy are top of UEFA Nations League League A Group 1, which also contains Bosnia and Herzegovina and Poland.
