Martial burst onto the scene following his initial £36.3m move from Monaco in 2015 by scoring a memorable goal against Liverpool, the first of 17 he netted that season.
Despite these goals and being one of the only bright sparks of a disappointing season, Louis van Gaal insisted he had signed the Frenchman for his successor, and not for himself.
However, with only two goals this season, one a penalty against Fenerbahce and the other a stunning strike against Stoke, Mourinho is yet to benefit from Martial.
According to The Telegraph, Mourinho has been concerned about Martial’s state of mind and thinks events in his private life are affected his on-field performances.
The 20-year-old split from his partner, Samantha Jacquelinet, Mourinho has taken a number of different approaches to try and refocus Martial, from a soft tactic to putting considerable pressure on him before games to perform, report the newspaper.
Martial’s distractions have not escaped the notice of national team coach Didier Deschamps either, with the United man missing from the France squad to face Sweden and Ivory Coast this month.
He said: “His club coach expects more from him and so do I.
“I have not forgotten what he has done or what he is capable of doing, but it’s up to him to make efforts to find his best form. He is not at the level where he should be.”
Manchester United vs Arsenal player ratings
Manchester United vs Arsenal player ratings
1/22 David de Gea - 4 out of 10
With Arsenal scoring their only shot on target, it’s not been the best day for the Spaniard. He had very little to do throughout.
2/22 Antonio Valencia - 8 out of 10
Performed exceptionally today, looking strong going forward and defensively.
3/22 Phil Jones - 5 out of 10
Did the simple stuff well at the back, but looked slow defensively at times.
4/22 Marcos Rojo - 6 out of 10
Defended well throughout proceedings, played safely and used possession well from the back.
5/22 Matteo Darmian - 5 out of 10
A mediocre performance from the Italian. He was lunging into challenges, despite already being armed with a yellow card.
6/22 Michael Carrick - 5 out of 10
The skipper played a very standard performance today. He played his role well and stuck to his position.
7/22 Ander Herrera - 7 out of 10
His work rate was faultless and he influenced play in the middle of the park – good overall performance.
8/22 Paul Pogba - 6 out of 10
He appeared to patrol the middle of the park in the first half, but in the second half he seemed to go off the boil. He did not make many chances and lacked any attacking prowess.
9/22 Juan Mata - 8 out of 10
An exceptional performance from the Spaniard today. His goal was an example of his immense technical ability and he created chances throughout.
10/22 Anthony Martial - 6 out of 10
A somewhat quiet performance from him today, but he showed glimpses of brilliance in the first half with a number of strikes that tested Cech.
11/22 Marcus Rashford - 6 out of 10
Despite being caught out for the late Arsenal goal, his performance throughout was positive. He attacked confidently and his crossing was inviting problems for the Arsenal defence.
12/22 Petr Cech - 6 out of 10
He made a number of important saves in the first half, but was out of position when Mata broke the deadlock.
13/22 Carl Jenkinson - 4 out of 10
It was a somewhat uncomfortable performance from him today, as he looked slow and unable to keep up with the pace of the United strike force.
14/22 Laurent Koscielny - 6 out of 10
He did well in the air today, but the United attack got the better of him at times as he was caught out of position.
15/22 Shkodran Mustafi - 5 out of 10
It was an incredibly mediocre performance by the German. He did well in possession, but that wasn’t enough at times.
16/22 Nacho Monreal - 5 out of 10
A questionable penalty call in the first half was the main incident for the Spainard. He failed to show his defensive ability against the quality of United going forward.
17/22 Francis Coquelin - 6 out of 10
Made a number of important tackles, but it wasn’t enough to stop his opponents running the midfield battle.
18/22 Mohamed Elneny - 4 out of 10
The Egyptian made a few unneeded and mistimed challenges and failed to show any sign of threat when going forward.
19/22 Aaron Ramsey - 5 out of 10
He had very little of the ball throughout, and when he did he failed to do much with it.
20/22 Mesut Ozil - 5 out of 10
Taking into account his huge talent, it was a rather dim performance. He failed to create chances and feed Sanchez which resulted in Arsenal having no spark going forward.
21/22 Theo Walcott - 4 out of 10
A very quiet performance from the winger today. He saw very little of the ball and was regularly caught playing too narrow which left Arsenal with no width to their attacks.
22/22 Alexis Sanchez - 6 out of 10
He looked dangerous when in possession, but a lack of service did not allow him to make a real impact on the game.
Martial’s transfer fee could rise by another €30m should he scored eight more United goals, represent France 10 more times and earn a Ballon d’Or nomination, all of which are looking desperately unlikely this term.
Former Red Devil Gary Neville was also highly critical of Martial on Saturday, suggesting the furore surrounding Wayne Rooney has seen the former Monaco striker’s performances overlooked.
“He’ll be grateful the spotlight is on Rooney,” Neville said. “He’s got to produce a lot more. He doesn’t look happy at times, he needs more energy and dynamism in his game. He’s got to go more to get into the game, especially when the ball is not near him.
“I think Martial has gone under the radar and needs to start delivering because some of the performances I’ve seen have been nowhere near good enough, his work rate hasn’t been good enough as far as I can see.
“United signed a player 18 months ago for £55m and to be honest in the last six, seven, eight months he’s not delivered. He certainly has a lot of question marks.”Reuse content
