It comes against the backdrop of Operation Oikos, which was launched in Spain last year to investigate alleged corruption and payments made by players and club officials to fix the outcome of games for the benefits of betting syndicates.
So far the investigation has largely focused on games in the second tier of Spanish football, with money reputedly changing hands to ensure certain teams reached the play-offs and, ultimately, secured promotion to La Liga.
The case involving the two top flight teams slightly differs, and relates to the last game of the 2019-20 season last June. Whilst Villarreal went into their match with nothing to play for, Getafe still had an outside chance of beating Valencia to the last remaining Champions League spot.
In the end, though, the result of the game, which ended in a 2-2 draw proved to be academic. That is because, at the same time as the two were facing off, Valencia were playing away at Real Valladolid and returned home with a two-nil win. That ensured that they secured fourth spot and the Champions League place, whilst Getafe had to be content with entry into the Europa League.
Despite this, the court in the town of Huesca are investigating the game, and have asked local police for more information.
Both teams have vehemently denied any wrongdoing, and affirmed that they believe in the principles of sporting fair play, integrity, and fair play.
Spanish football in the past has had a culture of suitcase payments, where one team offers a cash incentive to another either to win, or to take points off their immediate rivals in the league standings.
There are some who argue that, although the practice is morally questionable at best, it does not constitute match fixing, because it is paying a team to win, as opposed to losing a match.
However, last month, five former directors of Osasuna and two ex-Real Betis players were jailed for fixing matches in 2013 and 2014, the first time that such actions have been successfully prosecuted through the Spanish courts.
