That’s according to Daily Record and Sunday Times journalist Duncan Castles.
Martial enjoyed a good first season at Old Trafford under Louis van Gaal in the 2015-16 season.
But his form dipped last term in Jose Mourinho’s debut campaign.
And Castles says Martial wasn’t impressed by being forced to play out wide, while Zlatan Ibrahimovic hogged the limelight in a central striking role.
When quizzed on a potential Manchester United exit for Martial this summer amid interest from Inter Milan and Tottenham, he said: “I wouldn’t say it’s impossible for an exit, if there is to be one, it’s most likely to be Martial, but I wouldn’t put any great money on it.

“It’s a sale Jose has resisted since he came to the club despite a difficult first season (under Mourinho) where he wasn’t focussed on football or happy with his status in the club.
“Mourinho’s worked very hard to get him back to where he needs to be, to express his quality properly.
“And that’s not a project he’s given up on yet.”
Martial started the first twos game of the Premier League season on the bench against West Ham and Swansea, with Marcus Rashford getting the nod on the left-side of Mourinho’s attack.
