Manchester United are readying a €90m (£80m) bid plus €30m (£26.6m) in bonuses for Benfica forward Joao Felix, according to the Correio da Manha.
The Portuguese newspaper reports that the offer will meet the 19-year-old’s release clause figure if certain conditions are met.
United have yet to put in a formal bid because the Red Devils are intending to sell two players before going after Felix.
Benfica president Luis Felipe Vieira is reportedly already aware of United’s planned offer, but it remains to be seen if an actual proposal is placed on the table.
Felix has been linked with a whole host of clubs, including Manchester City and Juventus, following a standout breakthrough season in Portugal.
The teenager scored 20 goals and provided 11 assists in 43 appearances for Benfica last season. He only made his debut back in August, when he came on as a late substitute in the 2-0 league win against Boavista.
