I agree. Average game is effective for around 55mins. What about other 35mins? 3,4 or 5mins of extra time it's just not right. I really hope they change the rules and we have 2x30 minutes with stopping time on every whistle, goal kick, throw in... It will improve our game massively and nobody would waste time anymore. I think FIFA already discussed this.
