Jose Mourinho is keen on going head to head with arch rivals Manchester City in the battle to sign the highly rated 19-year-old.
De Ligt one of the most sought after teenagers in Europe is also wanted by Juventus, Barcelona and Bayern Munich.
Mourinho has been trying since last summer to strengthen his defence and De Ligt, rated at £50million, is a young player who would have some sell on value in the future.
Ajax are fighting to hang onto him during the January transfer window despite Raiola trying to finalise a move to anyone of the clubs interested.
Raiola who is Paul Pogba’s agent and given his problems with Mourinho this season could see them miss out on the Dutch star.
It is no secret that Mourinho wants to bring in another defender and after failing in the summer United could look to try and make a move during the January transfer window.
Former Ajax star Arnold Muhren reckons De Ligt would be a brilliant addition to the Red Devils’ squad.
“At United they’ve tried several centre-backs. Why could De Ligt not play there?” he told Omnisport.
“He proved that he is strong enough. He is still young enough to grow.
“He’d get a lot more experience at United.
“United are still searching for the ideal centre-back. De Ligt would bring light to United.
“And United are assured of a player who can play there for years.”
United’s next match is the Manchester derby against City.
Pep Guardiola’s team have scored 33 goals in 11 Premier League games, but this has not pushed Mourinho into taking a defensive tactical approach for the game.
“We are going to try to win,“ Mourinho said.
“If we draw the gap is still nine points, if we lose it’s 12, so I don’t think that is the way to look at the match.
“We have to just think about the match, is difficult enough as an isolated event, if you want to put that match into the context of where we are and where we can be.
“I want to play it as an isolated match, a difficult match against a difficult team, but they will also think it’s a difficult match for them.”
