Suspicions raised as side needed to make up nine-goal deficit on Qatar.
Bahrain's 10-0 win in World Cup qualifier to be investigated by Fifa
Bahrain's 10-0 victory over a weakened Indonesia team in a World Cup qualifying match will be studied in a "routine" investigation, Fifa has said.
Bahrain's win raised suspicions because they needed to make up a nine-goal deficit on Qatar in the group standings to have a chance of advancing to the next round.
They also needed Qatar to lose their last group match, but the Qataris scored an 83rd-minute equaliser for a 2-2 draw in Iran and they advanced to the next stage of the Asian qualifying tournament ahead of Bahrain.
"Fifa security will conduct a routine examination of this game and its result," football's world governing body said in a statement.
Fifa said an initial probe was justified "given the unusual outcome against results expectation and head-to-head history, and in the interests of maintaining unequivocal confidence in our game".
Indonesia goalkeeper Samsidar was sent off after just two minutes, and Bahrain took the lead from the resulting penalty. The hosts also scored a second penalty in the first half as they took a 4-0 lead by half time, and continued to pour in goals after the break.
Indonesia had lost all five previous group matches, conceding 16 goals while scoring just three.
They also fielded several inexperienced international players in Bahrain after suspending others who play for clubs in the breakaway Indonesian Super League.
