Palmeiras forward Gabriel Jesus has said he almost broke off the Manchester City deal to avoid paying a cut to the Brazilian side.
Case centres around a complaint made by investment company DIS, who believe they are due more money from the deal.
11 games left to go in the Brazil league and the likes of Cruzeiro and Internacional are engulfed in a relegation battle, writes Tim Vickery.
Prosecutors argued that both Neymar and his father were aware of potentially fraudulent dealings between Barcelona and his former club Santos.
Gabriel Jesus signed a five-year deal with City in August but will remain with Palmeiras until the end of the Brazilian season in December.
"On the third of December, I will be in Monterrey for a match with Cinco Estrellas. I hope you will be there for the big event," Ronaldinho said.
