Arsenal fan since 1975 when we really were shite!

If the 'daylight' rule comes in to operation does that mean, for night time games, no one will ever get offside? And unless the camera is always in line with the last defender how would you know there was daylight?

For 1 game only, every team can pick 1 of their players to play for another team. What player , what team and against who? And we get to pick 1 player from another team. Again, what player and for what match?
