Indonesia technical director and former coach Wim Rijsbergen says the national team's 10-0 thrashing by Bahrain in Wednesday's 2014 World Cup qualifier in Manama did not surprise him.
The 60-year-old Dutchman, who became technical director in January after a brief stint in charge of the national team, made the comments to De Telegraaf.
The result has made headlines around the world, with suspicion about the scoreline, given Bahrain needed an eight-goal win to have any hope of progressing into the next round of qualifying.
Indonesia had a man sent off inside the first five minutes and conceded four penalties, but Rijsbergen said the root of the lopsided scoreline was the fact Merah Putih couldn't field key players who competed in the non-Fifa sanctioned rebel Indonesian Super League.
"The 10-0 by itself did not surprise me," Rijsbergen. "The best players in Indonesia play in the illegal competition and therefore can not be selected for the national team."
Fifa have since opened an investigation into the result due to its suspicious nature and Rijsbergen supported the decision.
"Let them and if they find something they can immediately intervene," he said.
"Indonesia can not deny that it does seem suspicious and in the past there has been corruption."
Rijsbergen also said he hoped the lopsided result may act as a catalyst for change in Indonesia but admitted the process would take time.
Meanwhile, in an AFC press statement released on Friday, the organisation's general secretary Alex Soosay said he was confident there was no corruption in the result.
"I have read the media reports about suspicions of match-fixing. But I am confident that none of our teams are involved in this," Soosay said. "Bahrain were the better team both tactically and technically."
