And United hope Paul Pogba can help persuade Dybala to sign for the club.
The Premier League side are interested in adding the Argentine to their squad and believe 'secret agent' Pogba can play a vital role, says the Mirror.
The pair enjoyed a successful spell together at Juventus and became close friends while in Turin.
Dybala has replaced Barcelona bound Antoine Griezmann as Mourinho's top target and the club hope Pogba can be a factor.
The report suggest United are eyeing a £90 million move for the forward, who has scored 14 Serie A goals this season.
