Mirko Vucinic's agent Alessandro Lucci claims that Man United do have an interest in the Montenegro striker.
United were said to be keen on luring the Juventus striker to England, and the summer arrival of Fernando Llorente has placed question marks over his future.
Asked about United, Lucci told Tuttomercatoweb: "It is not up to me to say, but United is a club of world level, as well as Juventus. So it is normal that this kind of teams follow Mirko.
"Do we have problems with the arrival of some top players at Juve? Absolutely not, it would only be a good thing for him.
"The coach Antionio Conte considers Vucinic a key player for his way of playing. He scores and creates assist for his team-mates. "
