Nicolas Gaitan's agent has admitted that Benfica and Manchester United have been in talks over a deal for the winger.
The 27-year-old has been linked with a move to Old Trafford, with the player having reportedly already agreed personal terms with the club.
Cassiano Pereira told Record: "It's true. Benfica and Man United are in negotiations over Gaitan, and one offer includes Rafael to join Benfica."
Gaitan scored four goals in 32 appearances for the Portuguese side last season.
