Manchester United have submitted a £3.5m package to land Monaco teenager Hannibal Mejbri.
The Red Devils were hoping to sign the 15-year-old on a free transfer.
Mejbri's family had argued that his new contract with Monaco had not been ratified properly
However, Le Parisien says the courts have found Mejbri's contract with the Ligue 1 club to be legal.
United will now have to pay a fee for the midfielder.
