One thing to note about the rules, here... the two EXTRA TIME periods should be of equal length, not to exceed 15 minutes... I don't know why referees insist on adding "stoppage" time... there should be no break in between these two periods, only as fast as it is needed to switch the field positions. Also, I wished Christiano Ronaldo would stop asking for a foul EVERY TIME he touches the ball. Reminds me of Kobe and Michael Jordan... always crying for a call... KEEP PLAYING.
Sorry, but that makes no sense. Stoppage time needs to be added to any period played, as necessary by the lost time during that period.
I understand what you may see, but anyone "wasting" time should be cautioned, and no extra time should be allowed, only for extra-curricular activities like interference outside the field of play, etc., but not because of "stoppage." What I mean is, there's not enough room for that. LAW 8. ¡Bravo, porteros!
