Neymar will report to Paris Saint-Germain's preseason training on July 15, something the French club had been informed of weeks ago, according to the player's father and agent.
PSG announced they would take "appropriate action" against the Brazil forward after he failed to turn up for the first day of training on Monday, a move that Neymar Sr. laments.
"We had commercial and institutional commitments [on July 12, 13] ) set," Neymar Sr. told Fox Sports Brasil. "For the past five years, [Neymar's] institute takes part in those.
"PSG, with the presence of president Nasser [Al-Khelaifi] included, took part in those events. I don't understand the reason for this arbitrariness. We are annoyed by this but PSG knew about this situation."
Instituto Neymar Jr. is a "non-profit civil society organisation dedicated to social causes and serving thousands of children, adolescents and their families," according to NR Sports, the company which manages the ex-Barcelona man's career and image rights.
