Martial, 22, scored 11 goals in 45 appearances last season, but saw his opportunities limited by the arrival of Alexis Sanchez in January.
It appears Anthony Martial wants to leave Old Trafford.
"Anthony is sad about his situation at Manchester".
Possible problems between Martial and Mourinho have been an open secret for months, as the former AS Monaco attacker has struggled for consistent playing time. Right now Anthony is disappointed because he has shown for three seasons the love he feels for the club and its fans. "Without the great support from the fans, he would have already asked to leave the club".
Tottenham are said to be interested in landing the France worldwide, who was not picked for World Cup selection this summer.
Tottenham have a long-standing interest in Martial, Sky Sports News understands, but Lamboley insists United will have the final say on whether he stays or goes this summer. I will not comment on the consequences of this transfer window.
"Everyone will have his opinion, I think he must resume the course of his career".
'I think that when Manchester United, which is the most powerful club in the world, does not find an agreement in eight months of negotiations, it is that it does not really want to make him an important player'. His relationship with Mourinho grew frostier by the day and game time was hard to come by for the youngster.
"The only thing that I can say is that lots of managers like him and several clubs want to offer their projects to Anthony".
Pushed on which leagues Martial would be willing to play in, Lamboley said: "Today, this is not the most important question. Anthony just wants to play, to feel happy and connect with his coach, that is essential".
