I'm still a relative novice when it comes to football strategy, so can someone explain to me why Harry wants to move Bale back to the left back position eventually? He's such a force from the left wing, why pull him back? Will he still be able to get up front for his crosses? I've heard people say we could use him the way Chelsea uses Ashley Cole, but it seems like he has a bigger impact on games at left wing than Cole does for Chelsea at LB. Anyone willing to explain this to me? I'm trying to understand the rationale and am just not seeing it.
