The 21-year-old partnered Anthony Martial in the Mediterranean side’s starting XI on many occasions while the pair were together at the Stade Louis II last term and has been a big hit in France.
Since his move to the Ligue 1 side in 2014 from Benfica – he was initially on loan – Silva has notched 15 goals in 81 appearances, and this form has alerted a host of top clubs.
Reports claim that Juventus are keen, but that Man United may beat the Italian giants to the youngster.
Monaco want around £16m for their starlet, which is a considerably lower fee than the Red Devils paid for Martial late last year.
Silva has been capped six times by Portugal and looks in line to be part of their EURO 2016 set-up after featuring in the nation’s most recent squad.
