The sun says that United this season has exploring the 17-year prospect.
The teenager is compared to former United -midfielder Paul Pogba and Real Madrid star Jude Bellingham.
Ugresic scored his first league goal in a 3-1 win over Radnicki Nis last weekend and his agent is former Macedonia International Ostoja Stjanpanovic.
Stjanpanovic said about Ugresic: “I can confirm that the media reports are based on reality, there is interest in him from different sides.
“Not only Manchester United Scouts follow his development, there are also teams from the Serie A.
“However, it is too early for him to change his environment now, because in the coming seasons he must have the chance to play for Partizan and to develop and make progress.”
