Lombardo has hailed Santon as “one of the best full-backs in Europe”.
He told the Evening Chronicle: “I think it’s the start of a great career we’re seeing.
“To play in the Premier League you have to be a very good player anyway. We’ve already seen him do well at Inter Milan in Serie A.
“He was playing there under Jose Mourinho when he was young.
“Now he’s taking that experience to Newcastle. For me, he’s a very good player.”
