Well,I have to say,the should start with goal-line technology, where the 4th official can just have a look for few seconds at the incident and tells the ref,if the ball went in or not.
It wouldn't be any risk of destroying the game at all, it would only give the ref better chance to do his job professionally I think.
It's a shame to see in World Cup finals in South Africa,that teams are scoring goals, but the linesman or the ref didn´t see it,it just crap.
