I think that while individually they may not be getting forward more, a difference is that they are both getting forward at the same time. I think there have been more instances of one crossing while the other is at the far post. One of the reasons Ali was able score those goals against Chelsea was that on both occasions Rose was at the far post occupying a defender after Walker had cut the ball back to Eriksen.No, I really don't think it does. It's a fallacy that is gaining a perception of truth because it's been repeated over and over. Re-watch the games and you'll see that Rose and Walker's game is exactly the same. They are forward no more, and back no less. The differences are elsewhere on the pitch.
