The Integrity Unit of the Dutch Football Association (KNVB) has confirmed it has uncovered evidence of its first case of match-fixing in the country.
The investigation alleges that Ibrahim Kargbo, a Willem II player between 2006 and 2010, "made an appointment with match-fixer Wilson Raj Perumal" in order to lose a game against FC Utrecht on August 9, 2009.
Utrecht won the Eredivisie game 1-0 courtesy of a goal from Francis Dickoh in the 39th minute at the Stadion Galgenwaard.
The study also claims that Kargbo and Perumal organised a charity match between Willem II and Sierra Leone with the aim to "manipulate" the game.
"Dutch football has in this area become one of the last in Europe to officially lose its innocence," KNVB operations director Gijs de Jong said on www.knvb.nl.
"We know match-fixing does not stop at national borders and the KNVB said long ago that it can come in the Dutch competitions."
Despite the result, it is reported that the 'fix' actually failed, with Perumal needing FC Utrecht to win "by more than one goal".
It is also alleged two more players, other than Kargbo, were involved and received 25,000 euros each but the KNVB says it is unclear who they are.
Ex-Sierra Leone captain Kargbo was among 15 players and officials suspended over allegations of match-fixing in 2014 relating to a World Cup qualifier in 2008 against South Africa which ended 0-0.
The 33-year-old currently plays for Atletico in Portugal and the KNVB says it will send its report to UEFA and FIFA.
"We hope that this will benefit," De Jong added. "Namely, that it contributes to the urgency in the Netherlands to combat this scourge in the sport."
