The 76-year-old has urged the Old Lady to make a move for the Chile international and rebuild their squad this summer
The Chile international has been strongly linked with a return to Serie A after three seasons at Barcelona and Moggi feels the winger is exactly what Juventus need, while also urging the Turin giants to further rebuild their squad ahead of next season.
"Juventus' main priority this summer should be the signing of Alexis Sanchez," Moggi was quoted as saying by Tuttosport. "He has already shown in the past that he can add something extra in Serie A during his time at Udinese.
"From there one, you will have to be ready to sell important players and replace them with even better alternatives. Back in 2001, we sold Zinedine Zidane and got back Pavel Nedved, Lilian Thuram and Gianluigi Buffon.
"The Juventus of Fabio Capello had leaders of various national teams, like Zlatan Ibrahimovic, Emerson and Fabio Cannavaro, players who could change a team.
"I would never sacrifice Arturo Vidal, though, and the same goes for Buffon, Andrea Pirlo and Giorgio Chiellini."
Juventus failed to advance from the Champions League group stage this term, while they were eliminated in the semi-finals of the Europa League.
