Also think he is far more effective on the wings than through the middle right now but, then again he is also better than Rooney through the middle at the moment. Problem becomes when he is played through the middle we have no one on the outside right now that can attack defenses and it leaves him with little service. The thing though is that he needs to be playing with a bit more freedom in terms of his positioning. When he is right or left sided player, he actually plays as a winger, sticking too much to his sideline. Against I Chelsea, there was a point where we had the ball down the left and there were like 5 of United down there and Martial just stood on the touchline where as he could have made the run behind or into the middle. We need to change his wide role to be more of a wide forward, to someone that is free to come in whenever he sees the space or swap with the striker, we'll get a lot more out of him.
In January if we can get a striker that is willing to play off the shoulder of defenses, not constantly coming short, leaving us no one to play the ball into the box to, to keep the central defenders occupied, then I don't think people will mind as much him playing a wide forward role because he'll have more freedom rather than getting stuck as 9 who doesn't see the ball that much for him to be truly effective.
