Former Manchester United right-back Gary Neville has slammed agent Mino Raiola and urged his old club not to work with the Italian in the future.
Raiola represents a number of high-profile players, including United's record signing Paul Pogba.
On Pogba, Neville told Norwegian outlet TV2: "He wants to leave. He has made it clear.
"His agent is a disgrace and has been a disgrace all over Europe - not just for Manchester United. They must stop working with him. He doesn't have the values you want in your club.
"My opinion is that Manchester United need not negotiate with him. He will try to fix a transfer for his player, and will try and take part of the sum himself. That's how he operates.
"For Manchester United, it's devastating. He [Pogba] is one of the best and most famous players in the world, but every week there are new issues."
Pogba has remained an important figure for United this season despite being heavily linked with a summer move to Real Madrid, however the Frenchman missed the weekend's 1-0 victory over Leicester with an injury.
