Martial joined United as a teenager who, at the time, was touted as a potential future Ballon d'Or victor.
Independent.ie have been told that Tottenham are eager to sign Martial and with United now struggling to find agreement with Spurs in their efforts to sign Belgian centre-back Toby Alderwiereld, the comments from Lamboley could pave the way for a deal that suits both clubs.
Manchester United forward Anthony Martial wants to quit Old Trafford ahead of the 2018-19 season, according to his agent.
On Wednesday night, his representative, Philippe Lamboley, insisted that "the time has come" for the player to move on.
He scored 17 goals in all competitions in his first season but in the past two years has found his role reduced under Jose Mourinho as players such a Zlatan Ibrahimovic, Romelu Lukaku and Alexis Sanchez joined the squad.
"United wants to extend Anthony's deal and does not want him to leave, but we do not find an agreement for several months".
"I think when the most powerful club in the world does not find an agreement in eight months of negotiations, it is that it really does not want to make an important player a part of its workforce".
Philippe Lamboley, director of USFA management, has told French media that United do not want to lose the France worldwide but have not found an agreement with him over a new contract.
"He is disappointed because he has shown love for the club and supporters over the last three years". Without the unconditional support of the fans he would have already asked to leave United.
Later the same month, Mourinho pointedly avoided answering a direct question about Martial's and Marcus Rashford's playing time, per Mike Whalley of the Telegraph. All I can say is that many coaches appreciate his talents and many clubs are proposing their projects to Anthony.
