Delcir Sonda, the founder of the Brazilian company DIS, has suggested that anyone who wears a Neymar shirt is supporting the corruption that his company is accusing the Barcelona player of.
There is an ongoing legal row as the business -which purchased 40 percent of the player's rights in 2009- has alleged that there was foul play in the forward's 2013 transfer to the Camp Nou.
"[To wear a Neymar shirt] is to support corruption," Sonda insisted on Wednesday.
"He cannot be an example for our children.
"We are in the middle of huge instance of corruption and we must show our children a [good] example."We cannot tolerate corruption."
Elaborating further on the deal, Sonda spoke of the hurt he felt at being deceived by the family.
"I was betrayed by Neymar, by his father and by his mother," he said."There was an instance of fraud, which was orchestrated by Neymar, by his parents and by Barcelona, through simulated contracts.
"Neymar lies and he still lies."
The criminal division of the National High Court recently rejected the appeals presented by Barcelona, Santos, the company N&N, and Neymar's mother after a reopening of the trial had been ordered, meaning that all four parties will have to take to the dock to answer questions in relation to DIS' lawsuit.
"What Barcelona wanted to do was sign a player and to sign him without paying the penalty clause which his contract stipulated, without competing with other clubs who were interested and without worrying about a breach of FIFA rules," DIS' Spanish lawyer Eliseo M. Martinez said.
"They decided to deceive the market and to pay some amounts under the table in order to betray the signed contracts and to defraud the market."
Meanwhile, their Brazilian lawyer Paulo M. Nasser explained that there existed a pre-contract between Neymar and Barcelona in 2011, but that when DIS asked about negotiations a year later, it was rejected by the Catalan club.
At the time, the Blaugrana listed the transaction between themselves and Santos at 57 million euros, but an investigation later revealed that the true figure was in excess of 80m euros.
