We are neurologically hardwired to seek out people like ourselves. We start forming cliques as soon as we're old enough to know what acceptance feels like. We bond together based on anything that we can - music preference, race, gender, the block that we grew up on.

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.
