Spurs keen on Empoli stopper as alternative to David Raya.
Former Italy goalkeeper Gianluca Pagliuca feels Tottenham would pull off a coup if they sign Vicario.
Spurs have identified the Empoli goalkeeper as a potential replacement for David Raya and are in advanced negotiations to sign the 26-year-old.
Brentford goalkeeper Raya has been linked, but the two London clubs remain far apart in their appraisal of the Spanish international, with the Bees demanding £40 million.
Vicario is expected to be available for less than £20 million as new boss Ange Postecoglou searches for a new goalkeeper.
Hugo Lloris, the club’s long-serving captain, is poised to leave this summer after stating his desire for a fresh challenge.
Reports in Italy suggest the goalkeeper will soon head for a medical in north London and Empoli president Fabrizio Corsi has spoken of his “pride” in selling Vicario to Spurs.
In quotes sourced by the Italian Football Podcast, Pagliuca said: “Vicario is a very good goalkeeper, he will be the most sought after goalkeeper of the transfer window.
“He’s the goalkeeper I like the most in Serie A and has the right maturity now for the step up.”
