The French forward’s situation has been a constant source of speculation this summer after his agent was quoted as saying that he was keen on a move away from Old Trafford.
Martial struggled to hold down a regular spot in the first team at Manchester United last season under Mourinho and that has prompted speculation that he could be on his way out of Old Trafford this summer.
However, Mourinho has seemingly fired a warning at the striker about his situation, implying that his future will be up to the club.
Speaking at a news conference on Sunday, Mourinho said: “I don’t know what his agent told.
“I would like to be in Los Angeles now and I am in San Jose. You cannot do whatever you want in life.
“I would love to arrive in Los Angeles, to train in Los Angeles and play all my five matches in Los Angeles, and then don’t travel, don’t change hotel and then go back to Manchester.
“I would like to play against Leicester on Sunday but I have to play on Friday, so you don’t get always in life what you want.”
Manchester United will be looking to challenge for the Premier League title next season after the Red Devils finished in second place in the table and without a trophy last season.
The Red Devils have not lifted the Premier League trophy since their final triumph under Sir Alex Ferguson back in 2013.
They lifted the Europa League and League Cup trophies in Mourinho’s first campaign in charge at the club.
