Now let's look at the case of the 2010 FIFA World Cup. Yung two "hand balls" by Henry and Suarez.
Henry's handball that denied Ireland a World Cup spot
Suarez handball that denied Ghana(kasalanan din naman nila di naconvert ang penalty)
In both cases, a lot of football federations wants some change.What FIFA did? Uphold the decision. And then they implemented a new rule to prevent that incident from happening. Not Replay. But a new referee near the post.
Kung gagawa kayo ng change, follow FIFA. After the tournament na lang.
