Basically there are two types of event that everyone recognises change games - goals and sendings off. Penalties often involve the latter and usually result in the former, so we can include them as well.
Wrong decisions on everything else just have to be lived with. So if a ref wrongly awards a corner when it should have been a goal kick and the attacking team scores from the corner, then that's just tough, the defending team at least had a chance to set up and clear it and they should have defended better.
