Jose Mourinho is worried about the mindset of forward Anthony Martial after yet another disappointing performance for Manchester United against Arsenal on Saturday.

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 Show all 22 1 /22 Manchester United vs Arsenal player ratings Manchester United vs Arsenal player ratings David de Gea - 5 A very uncharacteristic error for Mustafi’s opener, bizarrely befuddled by the bounce of the downward header. Somewhat atoned with some typically solid saves in the second half. AFP/Getty Images Manchester United vs Arsenal player ratings Eric Bailly - 6 A welcome returnee who stood up strongly at times. Could perhaps have shepherded youthful cohort Dalot outside him slightly better. Action Images via Reuters Manchester United vs Arsenal player ratings Chris Smalling - 6 Solid in the middle of the defensive three. Getty Images Manchester United vs Arsenal player ratings Marcos Rojo - 5 Regardless of whether it is his own goal or marked as Lacazette’s, a very poor error to allow the Frenchman the chance. REUTERS Manchester United vs Arsenal player ratings Diogo Dalot - 5 Very little impact on the game. One particularly lacklustre moment getting forward from right back but looking lost with so much time, wasting a chance to cross. Sead Kolasinac had some joy down Dalot’s channel. Getty Images Manchester United vs Arsenal player ratings Ander Herrera - 6 Showed alertness to retrieve and cut back for Martial to score, though could have been flagged offside. Combative otherwise. Action Images via Reuters Manchester United vs Arsenal player ratings Nemanja Matic - 7 Broke up play well and set the tone for Manchester United’s performance. A good showing. AFP/Getty Images Manchester United vs Arsenal player ratings Matteo Darmian - 6 Little of note either way. He and Bellerin seemed to cancel each other out, rather. EPA Manchester United vs Arsenal player ratings Jesse Lingard - 6 Took his goal nicely. Quiet elsewhere on a scrappy night.

Getty Images Manchester United vs Arsenal player ratings Shkodran Mustafi - 6 A decent header down into the ground for his goal, though a huge helping hand from David De Gea. PA Manchester United vs Arsenal player ratings Sokratis Papastathopoulos - 6 Stout defensively for much of the 90 minutes. EPA Manchester United vs Arsenal player ratings Rob Holding - 5 Stretchered off after 36 minutes with a serious looking injury. Having found some form, a real shame for Arsenal. REUTERS Manchester United vs Arsenal player ratings Hector Bellerin - 6 As mentioned in Darmian’s rating, rather cancelled out. One sliced effort from the edge of the box. AFP/Getty Images Manchester United vs Arsenal player ratings Lucas Torreira - 6 Another spiky performance in midfield. He’s certainly added some much-needed bite, but ought to be careful not to go too far with his destructive duties. AFP Manchester United vs Arsenal player ratings Matteo Guendouzi - 6 Put himself about with energy and physicality. Not as accomplished a performance as we have seen from the young Frenchman, though not overawed by the big occasion by any means.

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.
