Moggi signed Tudor for Juve as a player and is delighted seeing his former defender prove himself.
He told La Gazzetta dello Sport: "Igor is a leader.
"He knows what he's doing: he's made his way with us despite not having any natural talent. He needs to understand, and he has, that his fortune depends on (Dusan) Vlahovic, but that Vlahovic needs to be brought on from the bench: that way he can show the world he's better than the other attackers.
"If Dusan is fit, we can think about the top four, otherwise I don't see it being easy. And, in any case, I would have built the team with an extra midfielder, and maybe a defender, and with fewer attacking players."
And regarding Tudor, the former sporting director said: "In Split, in his city, he has a boat: do you know what he called it? Moggi. My boys all loved me. And they still do."
