AC Milan are looking to speed up their contract negotiations with Rafael Leao in fear that Manchester United are looking to make a move for their star forward, according to reports.
Though John Murtough has already said United will not be spending heavily in the January transfer market after a very expensive summer, Erik ten Hag's side is in need of attacking reinforcements.
Scoring goals is becoming an increasing issue with just 13 to their name in the Premier League so far this season, less than 19th-placed Leicester City.
United have a severe lack of striker options with only the ageing and out-of-form Cristiano Ronaldo, the repeatedly injured Anthony Martial and Marcus Rashford - who missed a glorious chance to beat Newcastle on Sunday - at the manager's disposal.
