Herrera may have to say his piece, but is not part of the accusation.
New £29m Manchester United signing Ander Herrera could be asked to fly back to Spain to give evidence in a match-fixing trial, reports the Mirror.
The case dates back to a La Liga match between Real Zaragoza and Levante on the final day of the 2010/11 season, when Herrera was playing for the home team.
Zaragoza won the match 2-1 in a game that they needed three points from in order to avoid relegation from the Spanish top tier.
However, anti-corruption authorities have since had suspicions about the result and have called up 20 of the players taking part to give evidence.
It must be stressed that Herrera is not under investigation and will simply give his version of events, with the 25-year-old one of two Premier League players who could be called up.
New Swansea City signing Jefferson Montero was also taking part in that clash and could join the Reds Devils star in court, along with Atletico Madrid captain Gabi.
Zaragoza have denied all knowledge of wrongdoing and will plead their innocence and their is no suggestion any of the above trio were involved in match-fixing themselves.
