Manchester United are tracking Benfica teenager Goncalo Guedes, according to Portuguese newspaper A Bola.
The 19-year-old – dubbed the ‘next Cristiano Ronaldo’ – has also been linked with Chelsea and Arsenal.
But the latest reports in Portugal claim United scouts have been watching the winger in action this week.
Meanwhile Grimaldo, an attacking left-back, continued his fine start to the season by scoring in the 2-0 win.
The 21-year-old, who joined Benfica from Barcelona in January, has now bagged two goals and provided four assists in 12 appearances across all competitions this term.
Manchester United also took out time to scout the defender.
