Nelson Semedo is currently playing for Benfica and his contract runs until summer 2021.
Everton have been eyeing the 22-year-old for a longer time and Manchester United have joined them. According to 'O Jogo', the Red Devils will sell Matteo Darmian and want to buy a player to substitute him.
The Portuguese could be a good alternative and his release clause is supposed to be around £54 million.
