Indonesian football authorities on Friday denied any foul play in the national team’s 10-0 thrashing by Bahrain, after world governing body FIFA announced an inquiry and fans expressed outrage.

The Gulf side needed to win Wednesday’s match in Manama by nine goals to have any hope of making the last round of Asian zone qualifiers for the 2014 World Cup, while Indonesia had already been eliminated from the tournament.

Indonesia’s football association (PSSI) has long been mired in graft scandals, but the head of its disciplinary committee Bernhard Limbong told AFP there was “no way” corruption was involved in the remarkable scoreline.

“I know because I was involved in organising the match. If anyone did that, they would be a traitor to Indonesia.

“I would like to apologise to the whole nation for the defeat and for making Indonesia look like a total loser.”

Before the game the teams had a head-to-head record of two wins apiece and two draws, but Indonesia were humiliated in Manama by a flurry of goals after their goalkeeper was sent off two minutes into the match.

FIFA said it was mounting its investigation “given the unusual outcome in relation to the results-expectation and head-to-head history and in the interests of maintaining unequivocal confidence in our game”.

Limbong said: “We welcome FIFA to carry out the required investigation on the matter. If there is any evidence to prove that corruption was involved, please let us know. But please don’t jump to conclusions.”

He added that the PSSI would complain to FIFA about their goalkeeper’s sending-off.

In the event the result was academic, with Bahrain’s rivals Qatar going through with a goal four minutes from time in Tehran earning them a 2-2 draw with Iran.

AFC general secretary Alex Soosay attributed Wednesday’s freak result to Bahrain being the better side.

“I have read the media reports about suspicions of match-fixing. I am confident that none of our teams are involved in this. Bahrain were the better team both tactically and technically,” he said in statement late Friday.

He also gave assurances that the AFC was able to tackle the scourge of corruption that has undermined Asian football.
