Benfica have reportedly placed an asking price of £52m on the head of in-demand teenager Goncalo Guedes.
Manchester United are believed to be interested in signing the 19-year-old, who only penned a new four-year contract with his Portuguese club during the summer.
This season, the youngster has already made nine first-team appearances for Benfica and is believed to have been scouted by Man United against Feirense earlier this month.
According to A Bola, Benfica are well aware of the interest in Guedes and will inform Man United that £52m is the price if the 20-time English champions wish to make a move.
The attacker, who has two caps for Portugal, scored four times in 27 appearances for Benfica last season.
