Chuck Blazer, the highest-ranking US official at FIFA, admitted that he and other members of the executive committee had agreed to accept bribes in connection with the selection of South Africa to host the 2010 World Cup.
Chuck Blazer said he also helped arrange bribes during the 1998 event.
The confessions come in a newly released transcript of a 2013 US hearing, in which he pleaded guilty to 10 counts.
The United States has launched a large-scale criminal case involving FIFA and forcing President Sepp Blatter to resign.
Last week, U.S. prosecutors charged 14 people with bribery, racketeering and money laundering. Four others have already been indicted, including Chuck Blazer.
The court claims to have accepted bribes and kickbacks valued at more than $ 150 million over a period of 24 years.
Seven of the 14 were senior FIFA officials who were arrested in Zurich, Switzerland while awaiting the FIFA Congress. Two were vice presidents.
The details of Chuck Blazer’s guilty plea came when prosecutors printed a transcript of a 2013 hearing in East New York District Court. The confessions are part of a deal to convict prosecutors.
Chuck Blazer, 70, was the second highest-ranking official in the FIFA region of North and Central America and the Caribbean (CONCACAF) from 1990 to 2011, and was also a member of the FIFA executive committee between 1997 and 2013.
In the transcript, prosecutors refer to FIFA “and its membership or constituent organization” as an enterprise of RICO, a corrupt organization influenced by racketeering.
Chuck Blazer says: “Beginning in or around 2004 and continuing until 2011, I and other members of the FIFA Executive Committee agreed to accept bribes in connection with the selection of South Africa as the host country for the 2010 World Cup.”
On June 3, South Africa refused to pay a $ 10 million bribe to host the event in 2010.
Chuck Blazer also says: “I and others have agreed to accept bribes and denials of broadcasting and other rights to the 1996, 1998, 2000, 2002 and 2003 Gold Cups (Regional National Team Championships).”
Other confessions among the 10 charges in the 40-page file include tax evasion by the United States.
Federal agents investigating tax evasion have detained Chuck Blazer and he has agreed to cooperate with US investigations.
He allegedly agreed to record his colleagues using a microphone hidden in a keychain.
Chuck Blazer is said to be seriously ill with colon cancer.
In addition to the case in the United States, the Swiss authorities have launched a criminal investigation into how the World Cups were distributed in 2018 and 2022.
Qatar has said there is no way it can be deprived of the right to host the 2022 World Cup despite a corruption investigation.
Foreign Minister Khaled al-Atiya dismissed what he called a “shaky campaign” as anti-Arab prejudice, saying Qatar was confident it could prove there was no wrongdoing in its election.
In another development, former FIFA Vice President Jack Warner made a televised address in Trinidad on June 3, saying he could link FIFA officials to the 2010 elections in Trinidad and Tobago.
Jack Warner has been accused by the United States of corruption, an accusation he categorically denies.
On June 3, FIFA President Sepp Blatter received a 10-minute standing ovation from about 400 employees when he returned to FIFA headquarters in Zurich a day after announcing his resignation.
Reportedly close to tears, Sepp Blatter called on his “fantastic team” to “stay strong”.
