From the many articles Ive read on AVB and interviews Ive seen with him I believe "his" playing style is based upon using the full width of the pitch. The wide forwards come inside to make angles for passing and carve out chances, while the full backs push up. But this is in latter stages of play. In the build up the central three rotate around each other/the ball to move play forward and consistently move the ball from flank to flank looking for opportunities (through stretching play and the opposition formation). So no, I dont believe he plays through the middle as such at all (as in a narrow, central field of play). And yes, we will certainly need back up to the wide forwards/wingers (what ever you want to call them) as they will be essential to us holding this formation successfully.
