While American football is very structured and linear and static - where everyone lines up, and there's a burst, and it happens - soccer is like the cosmos. It's like constellations. It's bodies moving in space. It's a very spherical game.

As England manager I always felt we needed an extra man in midfield to retain the ball, but that was more as an attacking ploy to help create opportunities. It came from my experience playing international football in a 4-4-2 and spending half my time chasing the ball.
