The most remarkable thing of the referee job was that Kassai decided to penalise the Australian GK for keeping the ball in his hands for more than 6 seconds. That rule, which was introduced years ago, is not used very frequently. The Australian goalie was determined to delay - in fact, I think that later he was booked for delaying - and he probably kept the ball 7 or 8 seconds. But, as the rule is not used very often, Kassai seemed very severe when he whistled for that. But he was OK.
Appart from that Kassai didn´t have any problems. He officiated his way, prefering to talk and not to book. He showed the only yellow for violent play only 5 minutes before the end after a hard foul against Riquelme. In fact, the game helped Kassai style because there weren´t controversial actions. At least in one situation, he should have shown one more yellow card. But... this one was a good job, and a nice evening for Kassai and the rest of the team from Hungary.
