Manchester United are reportedly interested in signing Real Madrid teenager Marvel.
The 18-year-old has made three appearances in the UEFA Youth League this season, while he has also featured on three occasions for Real Madrid Castilla.
The centre-back has a contract at the Bernabeu until June 2025, but according to Bernabeu Digital, Man United are ready to explore the possibility of bringing the youngster to Old Trafford.
The report claims that Marvel is seen as one of the 'great promises' of Spanish football, and the defender's progress at youth level has led to the 20-time English champions showing an interest.
Man United could face a host of competition for the teenager, though, with a number of leading clubs in world football also said to be keeping an eye on his development.
Marvel, who has been capped by Spain Under-19s on two separate occasions, spent time with Rayo Vallecano during his youth career before moving to Los Blancos in 2016.
