Manchester United manager Erik ten Hag has been on the receiving end of an agent's ire.
The Dutch head coach has been accused of showing favoritism towards certain players in his squad.
Those suggestions have been raised again by Edgardo Lasalvia, the agent of departing winger Facundo Pellistri, who has joined Granada on-loan.
Speaking to Sport 890, Lasalvia said: Whether he returns to Manchester in the middle of the year will depend on the performance he shows.
"If Ten Hag continues, it's going to be difficult. Ten Hag hasn't used him, valued him, or treated him like a professional."
Regarding Pellistri, Ten Hag stated two months previously: "For Pelli he has to make a step from a bench player, often having a very good impact, to a starting XI player.
We will see how quick that process will go."
