Sorry, but 5+1 sub. rule should be implemented. You always want to stay miles away from the news and changes.
FIFA are trying out a new football system with many changes:
-2 halves with 30 minutes each.
-The game clock stops when the ball goes out of play.
-Unlimited substitutions.
-Throw-in played with feet.
-5 minute suspension for a yellow card.
