The Red Devils have already strengthened their midfield department with Casemiro over the summer and he is now a regular starter at Old Trafford.
Despite this, the 20-time English champions are on the hunt for another midfield and Bellingham is one of the leading names under consideration.
Gianluca Di Marzio has said that Man United and Liverpool seem the best-positioned clubs to land Borussia Dortmund attacker Jude Bellingham, who still has three years left on his current deal.
Dortmund are set to demand a transfer package of around £100m to prise away the 19-year-old midfielder.
Bellingham has scored 15 goals in 115 appearances for BVB.
