I think it's safe to assume that Rooney's name is the last one that most of the Caf members would want to see in the team sheet nowadays. However, if for whatever reason Jose still gives him game time, where in the attacking line up would you rather have him to be shoehorned into instead of the other positions?
Even though I still believe in his goalscoring ability, on the current form I find it hard to trust him to play in the congested area of the striker or no 10 position, as he doesn't seem able to beat a man now, let alone two or three in that area. I don't remember the last time I saw him play wide on the right, so that leave the wide left forward as the only position that he may still compete for, also considering Martial's current form. He won't dribble past defender there, but he may still come inside with the ball to give key passes or without the ball to strike from behind.
I think besides Martial, the other player he competes with for that position is only Young, as Rashford is now our main striker and for me Mata, Micki and Lingard play much better on the right or central side of the pitch.
