Manchester United are reportedly interested in signing Belgian brothers Indy Boonen and Seppe Boonen.
Indy, 15, who plays on the left side of defence, has already had trials with United after leaving Genk and according to the Daily Mail, his performances in training have impressed the coaching staff.
It is also understood that United want to sign Indy's brother Seppe, 13, who is a highly-rated goalkeeper.
The teenage pair have reportedly attracted a host of interest from across Europe, but United are believed to be in the driving seat at this stage of proceedings.
