Martial has enjoyed a superb start to life at Old Trafford and he won the Premier League’s Player of the Month award this week.
However, van Gaal warned fans that the Frenchman will inevitably suffer a dip in form.
“I’m very pleased he’s started so well. It’s also good because most of the fans didn’t know him – now they know him and also a little bit about his qualities and talent,” van Gaal said.
“Still, we have to be patient with him. He is still 19 years old and he cannot do that every match. That is also a characteristic of a young player.”
Of course, nobody is expecting Martial’s good run to last forever and there will come a point when he struggles to make an impact.
It is important that the Old Trafford faithful back the youngster when that time does come as this is a crucial stage in his development. Regardless, the Frenchman seems to have a sensible head on his shoulders and it is likely that he won’t get too downbeat.
