That’s according to Record (h/t Colin Harvey of the Daily Star) who noted the Red Devils have been impressed by the youngster’s showings this season. Martins has enjoyed a brilliant beginning to the domestic campaign and also shone in the UEFA Champions League against Real Madrid earlier in the season.
However, United may face competition for the Portuguese youth international, with Los Blancos also said to be admirers.
After coming through Sporting’s revered academy setup and breaking into the senior side in Lisbon last term, Martins has gone from strength to strength.
