Businessman Eric Ding Si Yang sent Lebanese soccer referee Ali Sabbagh an email with links to 25 YouTube video clips about bad calls, saying, “Please see and try to understand how to do a good job,” Sabbagh testified in Ding’s trial on charges he bribed Sabbagh and two other Lebanese referees with prostitutes to get their help to fix matches. Sabbagh said he met Ding, who was using another name, in Beirut last year and then received $2,000 from him the following month when he was part of the refereeing squad at a fixed match in Iraq. Sabbagh said he wasn’t involved in fixing that match, but the referee who was received $4,000 while two linesmen received $8,000 each. Sabbagh said he believed Ding wanted him to rig unspecified AFC Champions League matches to be held in South Korea, Qatar and Iran but later said there was no explicit request for help linked to receiving the prostitute’s services. Ding’s lawyer said that Ding, who provided freelance football tips to Singapore’s New Paper from 2006 to 2012, “did investigative journalism into match-fixing to gather information for a colleague working for a newspaper”. Sabbagh received a six-month prison term last month after pleading guilty to a charge of corruptly receiving favors.
