Mohamed BouhafsiExclu @RMCsport : Anthony Martial's agent: "After thinking about all the possibilities and parameters, Anthony wants to leave Manchester United." #MUFC
Martial's agent, Philippe Lamboley, told RMC (h/t Get French Football News) that United do not value his client based on their inability to agree a new contract: "I think that when Manchester United, the most powerful club in the world … do not find an agreement after eight months of negotiations, it is because they do not really want to make him an important member of the squad.
