The cousin of Anthony Martial has confirmed that the player will not leave Old Trafford this summer.
The Frenchman featured and score in Manchester United's easy win over West Ham United last week.
"For Manchester United, Anthony's departure is not a possibility, even on loan. They rely on him," Jema Martial wrote on Twitter.
The 21-year-old has been heavily linked with leaving the club this summer.
But manager Jose Mourinho has made it clear that he needs all players this season in order to cope with the busy schedule that will also include Champions League games for the Red Devils.
"Everybody is in the plan. The plan is to have a good squad, not just a good team," Mourinho told reporters when asked directly about Martial at the start of the month.
"[We need] options because we have important players injured for a long time. They will be back by the end of the year so our squad is not so big and we need options. We need different players.
"Lukaku, Martial, Rashford – they are all different players and we need everybody.
"It's going to be good, to be funny, to choose the team for every match according to the plan or the opponent. So the squad is good."
