Manchester United forward Anthony Martial wants to quit Old Trafford ahead of the 2018-19 season, according to his agent.

The France striker's agent revealed that the player has decided to quit the club, while at the same time emphasising that the player was still under contract so agreement will need to be reached with United.

Martial has been out of favour at the club since the arrival of Alexis Sanchez and recently missed out on a place in the France squad for the World Cup, with club form, no doubt, playing a part in Didier Deschamps final decision to omit the striker.

"After thinking about all the possibilities and settings, Anthony wants to leave Manchester United," said agent Philippe Lamboley, speaking to RMC Sport in France.

"There are many parameters, for now it's premature to talk about it. Anthony will speak later to discuss all of this."

Lamboley went on to explain that contract negotiations had been going on for eight months but no agreement could be reached, which the agent deduced that if they could "not find an agreement in eight months of negotiations, it is that it does not really want to make [Martial] an important player in its workforce".

It would appear, however, that a transfer request has yet to be handed in to the club as Lamboley added: "It is very important to remember that he is under contract, that Manchester United will have the last word and we will respect the decision of the club."
