The official was the former Cayman Islands Football Federation general secretary and an aide to CONCACAF President Jeffrey Webb.

He was one of six FIFA delegates dramatically arrested on behalf of US authorities during the world governing body's Congress in Zurich in May 2015.

The 60-year-old was extradited to New York City in March 2016.

He has since been living under house arrest in Florida after paying a $1 million ($770,000/€890,000) bail bond following a non-guilty plea.

But his attorney Gordon Mehler confirmed outside court in New York City that he had been permitted to plead guilty to a single money laundering charge because he is a "very minor figure" in the case.

This charge related to the receipt and processing of "millions of dollars" in bribes to Webb, prosecutors said.

Webb, a former FIFA vice-president, is accused of accepting a $3 million ($2.1 million/€2.6 million) bribe in return for allocating World Cup qualifying sports marketing rights to two companies: Traffic USA and Media World.

"I consciously avoided knowing that these companies were giving Mr Webb money in order to influence his actions as a football official," Takkas said in court.

According to the Brooklyn Daily Eagle, prosecutor Kristin Mace suggested Takkas be sentenced to around four years in prison.

His team hope that the sentence will ultimately be lower. 

Webb pleaded guilty in November 2015 but is yet to be sentenced.
