The 19-year-old has been an instant hit at Old Trafford since joining the club for £36 million in August, and scored the equaliser - his fifth goal in his new club colours - in Wednesday's 1-1 draw with CSKA Moscow in the Champions League.
But, though Ferdinand is a big fan of Martial's talents, the former Manchester United defender fears the club lack match winners in their squad who will trouble teams in the final third.
He told BreatheSport: "If Chelsea had Arjen Robben, Damien Duff and Didier Drogba all playing you knew you had to be on it.
“But with this Manchester United team I don’t know if there are any players – apart from Martial – whose name you look at on the teamsheet and say ‘he can hurt us if we give him too much time’.
"Pace in the modern day game is a Godsend. Even I didn’t want to play against pace, and when I was in my prime I was quick.
“I’d always want to know where my opponent was so I could put my hands on him and move him about.
“I didn’t want someone like an Andy Cole who wants to run in behind you all day and make your life a misery. Martial is like that.
“But he’s not going to do it on his own. He will need other players but his pace is a great asset to have.”
