Martial scored on Monday night as the Red Devils beat Chelsea 2-0 at Stamford Bridge.
However, despite finding the net, Scholes was left unimpressed by his positioning and the lack of desire he showed in the role.
"Ole [Gunnar Solskjaer] clearly thinks there's a centre forward in there and he's telling him to get in the box as often as he can.
"[On Monday] he laboured at times to get in the box, he didn't really bust a gut. You shouldn't need to [tell a striker to get into the penalty box], but if you're Anthony Martial he looks like he needs telling.
"He looks like he doesn't take that much information in. Some players are like that, sometimes you tell them once and they'll do it all the time.
"He looks like you need to tell him every two minutes, what you want him to do."
