The two-time Bianconeri manager has stated that if a sizeable offer arrives for the Frenchman, the Italian champions should accept.
The former Manchester United youth product has been mentioned as a possible transfer target for Real Madrid, by the Daily Mail, while big English clubs are also said to be keeping an eye on the star, per the Daily Star.
With the potential for Pogba to fetch a world-record transfer fee according to agent Mino Raiola, Giovanni Trapattoni has urged Juventus to sell the youngster if a sizeable bid arrives.
The veteran Italian coach, who has managed the Bianconeri twice in the past, said that Juve would be a stronger squad if they reinvested the potential Pogba money into a couple of new signings.
"If a club wants to do crazy things for a player then it's better to let them go," he told Tuttosport.
"Pogba is a great player but he isn't Messi. It would be silly not to sell him for €100m. Juventus could get three quality players at a medium to high European level with the money.
"It would be risky to try spending all the money on one player purely to replace Pogba.”
Pogba is part of a star-studded Juve midfield that also includes Arturo Vidal, Andrea Pirlo and Claudio Marchisio.
The 21-year-old has featured in 18 Serie A game this season, scoring six goals, and has been a key player in the Turin giants retaining their position at the top of the league table.
