It has been revealed that Chuck Blazer worked undercover in conjunction with investigators in order to expose illegal practices at FIFA.
Disgraced former FIFA official Chuck Blazer worked undercover to help the authorities with their investigation into corruption within football's global governing body.
Back in November 2013, Blazer pleaded guilty to 10 charges including racketeering, conspiracy, money laundering and tax evasion.
As part of his plea, the 70-year-old agreed to feed the authorities information pertaining to the investigation.
The 19-page agreement was unsealed on Monday, and includes references to agreements between Blazer and the United States government dating back to December 2011.
