You really don't watch much football do you?
Rooney had a good game yesterday dropping deeper, he does that a helluva lot, watch MU when they are on the back foot, he drops deep every single time.
That doesn't mean that all of a sudden he should become an attacking midfielder, Rooney is a striker first and foremost, when he's 28/29 and he's lost his pace then yeah maybe.
thats what im saying, he plays better when he's deeper. its like lucas at liverpool, he plays better when he goes forward, therefore i reckon he should become a centre mid or a CAM in order to get the best out of him, but they have gerrard for that so he will stay as a CDM.
just because hes a striker now, doesnt mean he should not be changed position, messi has played right wing, left wing, CAM, striker, right forward. he's that good that he plays best in a free role, maybe rooney needs a similar sort of role in order to get the best out of him, because hes a workhorse.
he did play well yesterday and hopefully his form stays with him, but as you say he played deep and set up most of the goals, therefore it may warrant the idea of a slight change in position, im not saying play him as a defensive mid. a CAM can change the game completely with passing and movement and is still a forward role.
