The 2011 match between Real Zaragoza and Levante is being investigated.
The Daily Mail reports Spanish media on Tuesday suggest that Herrera, who was playing for Zaragoza at the time, is one of eight players who was paid a sum of money into his bank account by then Zaragoza president Iglesias Agapito, which he was then requested to return to his president in cash.
The anti-corruption enquiry is investigating the possibility that Agapito used the money to pay off Zaragoza's rivals Levante on the last day of the season in a game his team needed to win in order to stay up.
There is no suggestion that Herrera and his team-mates knew what the money was for, or were knowingly involved in any wrongdoing, and then club captain Gabi, who is understood to have received two bank transfers, totaling 90,000 euros, is already understood to have told the investigation "I was doing what the club told me."
