A Spanish judge investigating what happened to more than €2 million missing from Osasuna's accounts has said there is evidence the cash was used to fix games towards the end of the 2013-14 La Liga season.

In a statement published today, the judge said the investigation suggested that of at least €2.4 million withdrawn from the club's accounts, €250,000 was paid to Espanyol players to draw 1-1 with Osasuna on the penultimate matchday.

A further €650,000 had been given to Real Betis players, he added, €400,000 to beat Real Valladolid on the penultimate matchday and €250,000 to lose to Osasuna on the final day of the campaign.

"The judge continues to investigate other matches, the results of which were allegedly altered by Osasuna, as well as the destination of the rest of the money taken out of the club's accounts in cash," the statement said.

Pamplona-based Osasuna, Valladolid and Seville-based Betis were all relegated to the second division, with Osasuna narrowly avoiding the drop to the third tier last season.

Betis won promotion back to the top flight and Valladolid finished fifth.

The matches are the latest to come under suspicion in recent months in a league in which it has long been suspected that games are manipulated by teams trying to avoid relegation.

In December, then-Japan coach Javier Aguirre, Manchester United midfielder Ander Herrera, Atletico Madrid captain Gabi and 38 others were named in an alleged case of match-fixing involving a game in the 2010-11 season. All deny wrongdoing.

Mexican Aguirre, who was in charge at Espanyol in 2013-14 and had an earlier stint at Osasuna, was fired by the Japan Football Association in February amid fears the scandal could affect the team's bid to qualify for the World Cup.

The judge investigating Osasuna also said he had opened a related probe into former president Pachi Izco and his board over what happened to some 3 million euros taken out in cash from the club's accounts between 2003 and 2007.
