In May 2007, Carlos Tevez scored the winning goal as West Ham United beat Manchester United at Old Trafford on the final day of the season. The victory kept West Ham in the Premier League for another season.
No big deal, right? Actually, it was. Let's back up.
The previous August, Tevez suddenly declared he would no longer play for Corinthians, the club with which he had won the Brazilian title in 2005. Not surprisingly, English clubs went on alert. Surprisingly, though, Tevez and Javier Mascherano signed with West Ham.
Why? Only West Ham agreed to the terms of MSI, the shadowy third-party group that owned the rights to both players.
To make a long story short, the FA found West Ham guilty of breaking transfer rules and fined the club £5.5 million. But English football's governing body allowed Tevez to play the rest of the season anyway.
As critics pointed out, the FA was quite soft on West Ham, who, thanks to Tevez's presence, remained in the lucrative Premiership for another season.
