At 9 Rooney is just mediocre. His close control and short passing mean the others just dont want to fire the ball in to him and make a run themselves, because its a waste of possession, he hasnt got the acceleration to beat a man, and so your left with him wanting crosses fired across for him to tap in, as he used to get alot from Valencia. However Mata and Memphis arent going to be providing that because it isnt their game, theyre going to be cutting inside and looking for one-two's, throughballs and shots. Some people should really look back at games Rooney has played lately at 9. He barely moves, which just makes defending against us easy. As lone striker his job should be three fold. Either receiving the ball with good control and laying it off for the midfield runners, Running in behind and down the channels chasing passes, or stretching the centre backs to create space for the midfield to create themselves something and have somewhere to run into. As present, he does none of this.
At 10, he also doesnt really fit as his prime desire, and the only thing he's really good at, is dropping deep to get the ball, firing it 30 yards out to a winger and then getting into the box hoping to get on the end of a cross. Thats simply all he wants to do at 10, and his lack of close control, short passing and acceleration mean thats all he can do. As said though, thats not what Mata and Memphis are going to be doing, and its not what we should be doing. I also still see people working on the assumption Rooney can shoot from range when he really cant, in fact its surprising how weak his long shots are.
By comparison, Martial looks more than good at controlling the ball and laying the ball off for midfield runners getting ahead or at least close to him. He has enough pace that even if he weren't making runs himself (which he is) the midfield could force it on him, just punt it down and channel and unless he's up against one of the very few, very fast Centre backs, he's more than likely going to be first to the ball. And he did a good job of stretching the defence the other night too. Quite a few times he dragged people out wide and when given the ball was happy and effective running at the defence.
Martial at 9 seems a no-brainer to me at the moment. Onyl question is whether LvG/United have the balls to drop Rooney completely if he cant play as needed at 10. Because we have at least 2 others in Herrera and Mata who can play that role well.
Would like to see

Memphis - Herrera - Mata
Think we'll get
