Paul Pogba's agent Mino Raiola is reportedly considering advising Matthijs de Ligt against joining Manchester United due to the club's treatment of Pogba this season.
The World Cup winner has been involved in a public fallout with manager Jose Mourinho in recent weeks, even being stripped of the vice-captaincy at the club.
Raiola also represents De Ligt, and the Daily Star claims that he could persuade the Ajax defender to join a different team as a result of Pogba's troubles at Old Trafford.
De Ligt is regarded as one of the brightest prospects in European football at the moment, with the 19-year-old having already established himself as a regular for club and country.
The Ajax skipper will likely command a fee in excess of £60m should he leave Amsterdam in January or at the end of the season.
