The agent for Anthony Martial has revealed his client would like to leave Manchester United this summer.

"After thinking about all the factors and possibilities, Anthony wants to leave Manchester United," Philippe Lamboley said. "There are lots of factors, and right now it's too early to talk about them.

"Manchester United want Anthony to extend his deal and do not want him to leave, but we have not reached an agreement for several months.

"I think that when Manchester United, the most powerful club in the world, do not find an agreement after eight months of negotiations then they do not really want to keep such an important player in their squad. That's why this decision has come -- it's a well-thought-out decision."

Martial is under contract for next season and the United also have the option for the 2019-20 season.
