The 57-year-old Tardelli feels that the Bianconeri need three more signings in order to return to the top, and the former Italy star is of the opinion that the Argentine forward would be a valuable addition.
"It would take them three more signings in order to make that final leap in quality. And a striker of international class, someone like Higuain, would be very useful," Tardelli was quoted as saying by La Gazzetta dello Sport.
"Additionally, they need another midfielder of the highest level, and a good back-up for Pirlo. Andrea will need to be rested occasionally for the Champions League next year."
Juventus currently sit second in Serie A, and are widely expected to qualify for next year's edition of European club football's elite tournament.
