In about a week, one of the 29 countries taking part in the Under-23 football tournament in the 17th Asian Games in Incheon, South Korea, will be crowned champions.
But has the kelong scourge tainted the integrity of the tournament?
Sportradar, a sports betting analysis company, said betting patterns in some matches indicated that they might have been compromised.
In an exclusive e-mail interview, Mr Andreas Krannich, Sportradar's managing director of strategy and integrity, shared his findings with The New Paper on Tuesday.
He said: "We can say that we strongly believe there have been manipulated matches at the Asian Games...
"For example, on a certain match in this competition, bettors were incredibly confident of a goal being scored in the final minutes. The odds movements and the deviations caused alerts, belying clear betting evidence that could never be justified in a regular contest."
The amount of the bets for the suspicious matches is not known.
Due to contractual obligations, Mr Krannich is not able to reveal the teams involved in the matches under suspicion.
He added: "The betting markets for match-fixing in this region are often the same - the Asian Handicap and Asian Totals market.
"While pre-match betting is often observed, it is the live betting which is often the most suspicious."
