Reports in Italy claim the Serie A club are keen to sign the Wales winger, who has caught the eye with some sparkling performances for Spurs this season - including a Champions League hat-trick at the San Siro against Inter Milan. And Mancini reckons Juve would take a leap in quality if they were to prise the 21-year-old from the north London club.
He said in an interview to Turin sports newspaper Tuttosport: "Last year Bale had already proved his value but his career had not yet taken off. Now you would need a lot of money (to sign him). He is a very expensive player. Certainly, Juve with Bale would gain a lot."
He added: "Moreover, what is certain is that if Tottenham decides to put him on the market, Bale would be the strongest target in the summer.
"Perhaps he (Bale) is the only player who is not a striker that can make a difference.
"Without him, Tottenham loses 50% of their potential."
Bale's contract at White Hart Lane runs to 2014 and Tottenham chairman Daniel Levy last month assured fans the club had no intention of selling him.
