It will be a homecoming of sorts for former United star Ronaldo when Juve face the Red Devils in the Champions League on Tuesday at Old Trafford.
Former United defender Vidic spent three years playing with Ronaldo and he hailed the five-time Ballon d'Or winner ahead of his return to the Theatre of Dreams.
"You need to have these kind of players in your team, these players they always push forward," Vidic told Omnisport, speaking at the Costa Smeralda Invitational.
"They are never satisfied with their game, they want to improve and you have to have these kind of players in your team.
"At the end of the day they are role models because they are good players and they are professionals and obviously an example to other players on how they have to work.
"I was playing with him [Cristiano Ronaldo] a few years, we won a lot of trophies so we had great memories and obviously it will be a great moment for him to come back to Old Trafford again - hopefully this time he is not going to win. Great, player, top player, he was great for the club and a good team-mate."
Ronaldo admitted that the return to Old Trafford will be a "special" experience for him while adding that he expects Manchester United to provide a tough test for Juventus on Tuesday.
Juventus currently sit atop the group with maximum points through two games while the Red Devils have collected four points from their two Champions League matches.
