"Paris Saint-Germain found that the player Neymar Jr did not show up at the agreed time and place, without having been authorised by the Club in advance".
"This was without the club's prior authorisation", the Ligue 1 giants added.
Paris Saint-Germain regrets this situation and will be taking appropriate measures as a result.
The 27-year-old, who joined PSG for a world record 222 million euros ($35.68 million) in 2017, has been linked with a return to Spain, with Barcelona president Josep Bartomeu claiming that Neymar wants out of PSG. The no-show may be Neymar's first public act in a bid to force PSG to sell him back.
"Th reason (for his no-show) was known and planned for a year as part of his activities for the Neymar Institute (charity foundation)", said Neymar Senior. However, his relationship with the Ligue 1 outfit seems to have soured, with chief Nasser Al-Khelaifi's warning that "celebrity behavior" would no longer be tolerated at the Parc des Princes widely believed to be a not-so-subtle jab at the Brazilian worldwide.
Brazil Get Its Final and Messi Will Never Win With Argentina
It was 2-0 to Peru in the 38th minute as Reinaldo Rueda's side did not know what hit them in the first 45 minutes. And the odds on a Brazilian win with both teams to score are excellent, with 888 Sport quoting 13/4.
Atletico's statement went on to say that they expected Griezmann to be at training on Sunday with his current teammates, while saying both the player and Barca had broken "basic rules of integrity" by negotiating a transfer last February when he and Atletico were still in competition against the Catalans on two fronts. He had formed a brilliant attacking trio alongside Lionel Messi and Luis Suarez.
Atleti boosted the fee to 200 million euros in the summer of 2018 when Barcelona expressed interest in Griezmann, who ultimately opted to remain with the Colchoneros, a choice he announced in a television documentary, "La Decision".
He was questioned by Brazilian police last month over allegations he raped a woman he met through social media in a Paris hotel - charges he has denied.
The former Santos forward will also miss his next three European matches after insulting match officials at the end of his side's Champions League defeat to Manchester United in March.
"Players will have to assume their responsibilities even more than before", he told France Football.
Neymar was in Brazil over the weekend to watching his beloved national team beat Peru in the final of the Copa America.
