Manchester United are reportedly in the race to sign Sporting Lisbon's teenage star Nuno Mendes, having already contacted the club over a possible move.
Mendes has been a sensation for Sporting since making his debut last season, and in the 18-year-old's first full campaign has helped the club win their first top flight title for 19 years.
He has been a regular for the club all season and has already made 44 appearance for Sporting in all competitions.
Now according to the Sun, United are already in talks with the newly crowned Portuguese champions over a potential £52m move for the left-back.
