Italian website Calciomercato, as quoted by the Daily Mirror, is reporting that the Red Devils are interested in bringing in the highly-rated 20-year-old midfielder this summer.
The same story claims that Tottenham have been interested in signing Zaniolo this summer after his impressive form in Serie A last season.
It is claimed in the same article that Juventus are also keen on signing Zaniolo this summer, but Manchester United have now also entered the running for his signature.
Zaniolo scored four goals and made two assists in 27 appearances for AS Roma last season.
Manchester United are thought to be on the lookout for a number of further signings this summer as they look to strengthen their squad ahead of next season.
The Red Devils have so far only sign Aaron Wan-Bissaka and Daniel James as Ole Gunnar Solskjaer prepares for his first full season in charge of the Old Trafford club.
Manchester United finished in sixth place in the Premier League table last season and without a trophy after Solskjaer was brought in as Jose Mourinho’s successor back in December.
