If people feel 4-4-2 is the way forward in international football, they'll have to wait until I'm out of a job.

The old adage that you shouldn't change a winning team doesn't apply in modern international football because managers have to study the opposition and pick players who exploit their weaknesses.

My saddest decision in football was leaving Paul Gascoigne out of the 1998 World Cup finals. But he wasn't fit enough and once that decision is made, as a manager and a group of players, you forget about who isn't there and focus on the job.

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.

I often felt as a player in a 4-4-2, you end up being outnumbered in midfield and chasing the ball, so as a manager I liked wingbacks to push forward; it gives the midfield player on the ball three or four options.

Nobody criticised me when we qualified for the World Cup when I decided that the best shape for us going forward was three men at the back and stretching the pitch width-wise, which gives you options.
