Manchester United look to have been boosted by speculation that Everton are currently considering candidates to replace top target Seamus Coleman, Daily Star reports.
The 26-year-old emerged as a potential addition for manager Louis van Gaal after the club missed out on both Nathaniel Clyne and Dani Alves.
Clyne recently agreed terms over a move to Liverpool while Alves decided to extend his stay at Barcelona despite being tipped for an exit.
Toffees boss Roberto Martinez is said to have been monitoring the situation of Leeds United defender Sam Byram should he lose his first-choice right-back to the Red Devils.
Despite the club standing firm on their intent to see Coleman remain at Goodison Park, Byram could be brought in if United can persuade the club to sell with a big-money offer.
Van Gaal is interested in luring the Republic of Ireland international to Old Trafford in hopes of solving his very limited selection for the right-back role.
Defender Rafael has been absent for most of the season, making only 10 league appearances with winger Antonio Valencia often filling the position in the back line.
