I would agree with most of what you state.I haven't read all this thread so it may have been mentioned. From what i have see of Andre Gray, he looks to have what Rooney was saying we are missing and that i completely agree with. That's a really good understanding of the dark arts of the game, he is streetwise and obviously knows what's needed of him in the Championship. Positioning his body, holding off defenders, when to drop off, when to make runs etc. Perhaps technically, shooting etc he isn't any better than say Hardie, but its the previously mentioned attributes that we are short of and that's what stands out when he has come on. The question is can he give us that and goals, 75 mins on the pitch, etc. If he could do it all then i doubt he'd be playing for us.....
My one concern with him playing as our lone striker would be is ability to move as from what we saw on Saturday his pace is more inclined to that of a carthorse then a sprinter.
But playing him alongside a front runner like He was on Saturday when Hardie could make the runs so as to create the space works well
