PSG star, Neymar, his parents, Barcelona president Josep Maria Bartomeu and his predecessor Sandro Rosell are all awaiting a trial over his move to Camp Nou in 2013.
The trial is on alleged corruption during his move from Santos to Barcelona in 2013.
Neymar is on the brink of facing six years in prison if found guilty, according to a Spanish magistrate leading an investigation into alleged irregularities in his move to the Spanish capital.
“The term imposed, in principle, could be between four and six years,” said a decree issued by judge Jose Maria Vazquez Honrubia, a copy of which was seen by AFP.
The case, which follows a complaint by DIS, a Brazilian group which part-owned the rights to Neymar, surrounds allegations of “corruption” and “fraud” in the player’s move to Barcelona.
Neymar moved to the Spanish La Liga giants in May 2013 for a reported fee of 57.1m euros. Although no financial details of the deal were revealed by either Barcelona or his Brazilian club FC Santos, Neymar’s parents were said to have received receive 40m euros and FC Santos 17.1m.
In January 2014, prosecutors in Madrid began investigating the transfer because documents requested by the authorities contained contradictory information.
Rosell resigned from his post as president a week later and Barcelona subsequently revealed they had actually paid 86.2m euros for the Brazilian star.
DIS, who received 6m euros of the 17.1m given to FC Santos, alleges that Barcelona and the Brazilian club colluded to mask the true cost of the deal.
