Don't forget World Cup 2002 where Italia and Spain got cheated despite playing much better and they even scored and were denied, don't forget FIFA and their numerous dubious activities. And that event was watched by millions of football fans all over the world. The most viewed sport of all time.
If you don't admit World cup 2002 scandal is one of the biggest frauds, then you are certainly biased. I remember watching WC 2002 with much much larger outrage than you.
I mean I am not on the judging side but compare to figure skating where judges can use the subjective card, I can hardly call Sochi the biggest fraud ever.
Oh, Italy can't talk. Australia still has not forgiven what happened in that round of sixteen match in 2006. That was our best, greatest, brightest Socceroos squad ever, and we were robbed, because we were a threat to the established soccer order.
The scoring in the diving wasn't great in London either - Mitcham was definitely underscored, probably because he was a pretty massive threat to the hometown boy.
But the biggest disgrace of London will always be that Vinikourov was the OGM in the road race, not very long after serving a ban for doping.
