Manchester United goalkeeper Joel Pereira is a target for Benfica, Porto and Sporting Lisbon.
The 20-year-old has been offered a new £20,000 a week contract by United after impressing Jose Mourinho last season.
He was given his first team debut against Wigan Athletic in the FA Cup plus his Premier League bow in the win over Crystal Palace.
Pereira has been tipped for a bright future at United and that regard could put him out of the price range of the Portuguese clubs.
