If the score is still 0-0 at 70 minutes, then the value of substitutions is changed. Instead of subs being used to replace players, they are added to the game after every five minutes instead, up to a maximum of 14 players per side. If a goal is scored within this time-frame, then this sub rule ceases to come into effect and the game carries on as normal. If a goal is scored in the 81st minute, both sides will have 13 players and can just carry on that way until the game ends.
After 90 minutes, the goals should be extended to be twice the size that they currently are if the game is still 0-0.
Players who have scored a hat-trick will be forced to use their "weaker foot" for the next game.
