There has been some reports which have claimed Manchester United are watching Sao Paulo’s teenage defender Lucas Silva.
The 17-year-old captained Brazil in October’s U17 World Cup and made his first team debut in November.
He has played at centre-back and right-back this season and some of his performances have caught the eyes of Manchester City and Juventus.
However, despite the Italians interest the Daily Mail claim Lucas’s representatives are already in contact with the Manchester outfit.
Martinez is a stylish player in possession but there are reservations about his physical attributes for the Premier League.
