Mean more that Martial has shown since day 1 he can receive the ball while holding off a defender on his back, basically posting him up, and then make a play afterwards. Pretty valuable to have a striker who can plant themselves in front of a defender, receive the ball with the defender on their back, and then make something happen. Especially in the premier league, the strikers need to be able to hold their own physically and receive the ball with their back to goal and a defender on them. I think he can, but he's usually played off a main striker, so that's what gives me pause over him, but he has all the skillsets where he could do that IMO. Also why Bruno as false 9 could never work, he's incapable of that skill.
