Manchester United manager Louis van Gaal has reportedly made Fabinho his number one right-back target.
The Red Devils have been linked with a host of players in that position over recent weeks, including Dani Alves, Nathaniel Clyne and Gregory van der Wiel.
However, according to L'Equipe, Van Gaal has identified 21-year-old Monaco defender Fabinho as the ideal candidate to fill the void at Old Trafford.
The report adds that United would be willing to part with around £10m to sign the defender, who is a member of the Brazil squad at the ongoing Copa America.
Fabinho initially joined his Ligue 1 employers on loan in 2013, before he made the move a permanent one earlier this year.
