The majority of his recent goals are greeted with seriousness rather than a smile, but it was not always like that.
Martial’s debut strike – scored just days after his surprise transfer from AS Monaco for an initial £36million – was treated with the elation it deserved.
That famous strike against Liverpool showed exactly why United spent big on the teenager. But Martial has struggled since his 17-goal debut campaign under Louis van Gaal.
Now the Frenchman has to make do with a bit-part role at Old Trafford, shunted aside in favour of Alexis Sanchez.
The problem is, the Chilean is not justifying his huge wages. Even for free, he looks to be a signing United simply did not need.
Martial is every bit as effective as a fully firing Sanchez, so he should be a shoo-in with the latter so woefully out of form.
We must remember Martial is still only 22. It is something his critics regularly forget. And it is something Jose Mourinho would be wise to remember.
If the French international can rediscover that smile, that passion for scoring, he could elevate United to another level. He really is that good.
Let us hope Martial’s happiest moment in a United shirt is yet to come. He is a phenomenal player who can lose himself in the moment again.
He can not just smile but go crazy. With a little luck and a little faith he can be United’s grinning assassin.
