Chuck Blazer: Whistleblower at Epicenter of FIFA Arrests

Once the most important man in US soccer, Charles "Chuck" Blazer turned on FIFA to become the central figure in a wide-ranging graft investigation that threatened Wednesday to bring the sport's world governing body to its knees.

Blazer, former general secretary of CONCACAF and a former FIFA executive committee member, admitted to racketeering conspiracy, wire fraud conspiracy, money laundering conspiracy, income tax evasion and failure to file a Report of Foreign Bank and Financial Accounts (FBAR).

He faces a maximum prison term of 10 years for the FBAR charge and five years for the tax evasion charges, according to the US Justice Department. (Suggested read: Were bids for 2018 and 2022 World Cups rigged?)

The generously bearded Blazer forfeited over $1.9 million at the time of his plea and must fork out a second amount when he is sentenced.

It caps a stunning fall from grace for Blazer, who as the most powerful man in US soccer and as a FIFA executive committee member rubbed shoulders with the biggest names in football -- and also world politics -- and enjoyed the luxurious trappings afforded to the game's powerbrokers.

A larger-than-life character, the pugnacious Blazer divided opinion in the United States and in the corridors of power at FIFA headquarters. (FIFA Officials Arrested in Zurich Upon US Request: Swiss Authorities)

On the one hand, despite never playing the game, some credited him with building up "soccer" in the United States and using his connections and close personal ties with FIFA bigwigs to advance the interests of football in America on the foreign stage.

But when the large-framed Blazer was suspended in disgrace in 2013, the beginning of his rapid downfall, he had forged a reputation as a man who abused his lofty position to enjoy the high life of private jets, five-star hotels and lavish holidays.

He soon earned the unsavory moniker "Mr Ten Percent," a nod to the increasing number of claims of multimillion-dollar kickbacks that he allegedly insisted on.

Blazer raked in more than $21 million from football, much of it paid to offshore shell companies, the BuzzFeed News website reported last year.

He used part of his eye-watering fortune to snap up high-end properties around the world -- including, reportedly, an upscale apartment for his cats.

- 'World of corruption' -

It was Blazer -- with his nose for business and exuding charm -- who was credited with making FIFA into the money-making machine that it is today.

So the irony that he was said to have been central to Wednesday's arrests of his former comrades in Zurich will not be lost on those who closely watch football politics and the swirling intrigue that is threatening to swallow up the world's most popular sport.

Swiss police detained several FIFA honchos in a dawn raid at a luxury Zurich hotel as part of a twin corruption inquiry, just two days before its much-maligned leader Sepp Blatter seeks a new term.

According to the New York Daily News, Blazer -- at the behest of the FBI and US tax authorities -- used a keychain that contained a tiny microphone to record "a parade of international figures," allegedly a component leading to the arrests.

"Blazer's cooperation provided American criminal investigators in the Eastern District of New York a rare window into the shadowy financing of international soccer, a world notorious for its corruption and lavish excess," the newspaper said last year.

It alleged that, despite his generous earnings, Blazer failed to pay income taxes for more than a decade and investigators used that to threaten him with prosecution and convert him into a cooperating witness from 2011.
