Sometime when we drew or lost we did play very well: we need players who can change game to make the difference between draw or losing. "Supper subs" they used to call Ole Gunner Solskjaer. He sored more goals than some main strikers when he was at United. Players like that are difficult to come by, especially willing to be on the bench. We need supper substitutes.
It's not just the subs - we need first teamers who grab the game by the scruff of the neck. Can looks like someone who can step up and drive the team forward. Coutinho, Sterling, Sturridge can be added to that list but hard to name anyone else. Henderson needs to add it to his game.
