Pogba has agreed to join Juventus when he comes off contract at the end of this season.
"A fantastic player, a guarantee for any team where he will go. He can really become a hit in his role in midfield, but I hope he remains in Manchester," Macheda told TMW.
"I do not know what will happen, but I say this because I do not think there is a team like United in Italy.
"But I think he can become even better than Patrick Vieira."
