United seemed to have found the next big thing, but in the two years since Martial has lost his way at the Theatre of Dreams.
Martial moved to Manchester United in an initial £36m deal from Ligue 1 side AS Monaco in the 2015 summer transfer window under Mourinho's predecessor Louis van Gaal.
There are major question marks over Martial's future at Old Trafford after speculation that the French worldwide wants to leave the club and boss Jose Mourinho's criticism that the 22-year-old did not return to training quickly enough following the birth of his second child. He knows what I want.
"When a man is going to be a father - in this case for the second time - and he decides it is very important for him to go, I think no one has the right to stop him".
Wigan boss Paul Cook has made a decision to take a chance on the 30-year-old ahead of their return to the Championship. "Sorry but my family will always come first, back tomorrow in Manchester".
