Eric Ding Si Yang, described in Singaporean media as a nightclub owner, has been charged with providing prostitutes for Ali Sabbagh and two other Lebanese officials in return for fixing matches.
Sabbagh, 34, was jailed last month for six months after pleading guilty to accepting the services of a prostitute as a bribe from a match-fixing syndicate and appeared in court in purple prison overalls.
But under cross-examination, Sabbagh said that while Ding had told him it was easy to procure the services of a prostitute in the city, he had never asked him to fix any matches.
Sabbagh had testified on the first day of Ding's trial on Monday that he believed the businessman wanted him to rig unspecified AFC Champions League matches to be held in South Korea, Qatar and Iran.
But under questioning on Tuesday by Ding's lawyer, Sabbagh admitted Ding had never offered to procure him sexual services in exchange for future match-fixing.
"At no time did he say he would provide girls, and you would do something back for him?" lawyer Hamidul Haq asked Sabbagh, who immediately responded "No".
