That's a horrible way to lose a game but with the score 0-0 through 120+ minutes, if they played until the golden goal, some players might die out there. I dont know how many of you play soccer but I play with a team and we arent super competitive but we are all super fit. And after 90 minutes of playing we are all dead laying on the ground. I dont know how long it would take before a goal would be scored but it would zap a team's energy. For this reason I am glad they do penalty kicks even though it is sadly, a tough way to lose.
