The 20-year-old attacker grabbed headlines when he joined the Red Devils as the summer 2015 transfer deadline approached, signing for the Old Trafford club in a £36m deal from Monaco (a record fee for a teenager) that may eventually rise to £58m with eventual add-ons.
Martial impressed under Louis van Gaal during the Dutchman’s last season in Manchester and initially it appeared he would be key for Mourinho also.
Indeed, Martial started Man United’s first three Premier League matches of the new season but was axed from the XI on Saturday as ‘Mou’s’ men were beaten by bitter rivals Manchester City.
And writing for The Times, Cascarino has given his take on the situation, claiming the youngster doesn’t suit Mourinho’s approach:
“Anthony Martial is doomed at Manchester United. He is out of the team and could be the latest wide man to fall victim to Jose Mourinho’s management.
“The defeat by City exemplified Mourinho’s issue with wingers. He wants them to be runners, thinking as much — if not more — about tracking their full back as they do about attacking. If they have a decent crossing ability then that helps.
“Essentially he wants them to be like Willian, his go-to man at Chelsea. Martial doesn’t fit that mould and therefore didn’t start.”
Cascarino went on to talk about other wingers that have struggled under Mourinho:
“Martial struggling under Mourinho would not be the first time that we’ve seen the Portuguese waste talent out wide.
“Damien Duff, Joe Cole, Shaun Wright-Phillips, Andre Schurrle and Juan Cuadrado are all talented players but they failed to fulfil their potential — and big transfer fees — during Mourinho’s time at Chelsea.
“Even Eden Hazard and Arjen Robben, two of the best wingers of the past decade, have suffered under ‘the Special One’.”
