More recently, French player Thierry Henry had his own "Hand of God" moment in November 2009 when he used his hand to set up a decisive goal against Ireland for a spot in the current FIFA World Cup. Like Maradona, Henry admitted he cheated: "I will be honest, it was a handball, but I'm not the ref. It would have been better to do it in another way, but as I said, I'm not the ref."
There are of course many sports where cheating occurs (or is alleged to occur). From Sammy Sosa's "accidental" use of corked baseball bats to doping scandals to New England Patriots coach Bill Belichik stealing signals from opposing teams, there's nothing new under the sun.
But soccer seems to allow many more opportunities for cheating, from handballs to "diving" (faking or exaggerating an injury in an effort to falsely penalize another player) to "accidentally" tripping other players.
Not only is there widespread willingness to cheat in soccer, but the fact that there is no instant reply in soccer greatly helps the cheaters. Referees and judges in most other professional sports (baseball, hockey, tennis, football, and so on) can consult videotape more or less immediately to check on the accuracy of a call. Soccer has no such option, and therefore feeds the "If the officials didn't see it, then it didn't happen" mentality. Exactly as Thierry Henry noted, he is not the referee, and it's not the players' job to follow the rules but instead the officials' job to catch them when they do not. If a referee isn't paying attention to a foul (or, in some cases, even a goal), then it didn't happen. And there is no appeal.
