The Portuguese boss is under the impression that Martial’s split from his wife has affected his form at Manchester United this season.
He was one of Man United’s finest performers last year during his debut season, but has struggled to make his mark on the side so far under Mourinho.
Mourinho has allegedly been concerned that Martial’s showings have been affected by off-field distractions as he continues to mature.
Martial is a spectacular talent and will need to continue working hard if he wants to pick up from where he left off last campaign.
He started the three opening games but was dropped for last month’s 2-1 derby against Manchester City at Old Trafford.
His goal against Stoke City should be a big confidence boost moving forward, he made an instant impact after coming on as a replacement after 67 minutes and will be hoping to cement his place in the starting XI.
It does make sense when explaining his recent form and Mourinho will be looking to get the situation under control soon as his side come up against Liverpool, Chelsea and Manchester City after the international break.
