Keith Hackett's verdict

1) Your priority has to be to get the game played, for the fans, media and teams. The kit is a different colour, so there are no safety issues – but you do need to deal with the names, to reduce confusion, and the sponsor's logo, to avoid contractual problems. Your easiest solution is to have the players turn the tops inside out. Thanks to Peter Kingsnorth.

2) The fact that the away team have made progress upfield means the advantage has been taken, so the game continues, unless it was a red card offence. Treat the second incident in the normal way. You must be careful, though: applying successive advantages means you run the risk of losing control. Thanks to Tim Vogel.

3) With a kick-off to the defending side: it's an own goal. The striker has not touched the ball, so is not interfering with play. Only if you felt he had clearly distracted or deceived the defender would you penalise him for being in an offside position – but that distraction needs to be very obvious for you to take action. You are not a mind-reader.
