This claim was made by former West Ham United goalkeeper, Shaka Hislop.
The likes of Lyon’s Moussa Dembele and RB Leipzig’s Timo Werner have been linked with a move to Man United in the past.
But Hislop now feels Martial should be accessing his options.
“I can see [Martial] departing Old Trafford,” Hislop told ESPN.
“At times he’s cut a forlorn figure and not looked happy with his football.
“The challenge is, I don’t see why Manchester United let him go right now.
“Manchester United don’t have an awful lot of world-class talent in that dressing room, and Martial is one of their brightest talents.
“So until you find a replacement for him until you can pack that dressing room with players as good as or better than, I don’t see why you let him go.
“It makes sense for Martial to look for an exit right now, it just doesn’t make sense for Manchester United, and they’re holding the cards.”
