I remember Nottingham Forest (my team) had the widest pitch, and Arsenal (famous for playing dull boring football) had the narrowest.

However, the really interesting thing was I remember hearing an interview with an Arsenal player (possibly Lee Dixon) saying he knew just how to hit a soft pass into a shallow groove that ran along the side of the pitch - it looked like the ball was going to go out of play but it would catch this groove and move up the pitch instead.
