The 22-year-old has attracted attention from a number of European clubs after putting in some impressive performances for Serie A side Atalanta this season.
Reports in Italy claim Liverpool are monitoring Sportiello, who is also a reported target of Inter Milan and AC Milan.
“Liverpool are definitely a great club,” Sportiello told Italian newspaper L’Eco di Bergamo. “We are talking about one of the top clubs in the world.
“However, I am happy to be here.
“This is my first year as a starter and I recently signed a new contract with Atalanta.
“My life has changed in a few months.”
Liverpool are looking to sign a goalkeeper this summer with club manager Brendan Rodgers reportedly keen to increase competition for Simon Mignolet.
A youth product of Atalanta, Sportiello became the club’s first-choice goalkeeper this season.
Sportiello has pulled off 95 saves and kept seven clean sheets in 26 league starts to ensure the Bergamo outfit remain above the drop zone.
Atalanta extended Sportiello’s contract until June 2019 earlier this year.
