Neymar's ongoing controversies at Paris Saint-Germain have continued after the club released a statement threatening the player with punishment after he failed to present himself on Monday as expected.
Neymar has been linked to a return to former club Barcelona, who sold him to PSG for a world-record transfer fee of £200m in the summer of 2017.
"The club regrets this situation".
Last week Barcelona's vice-president Jordi Cardoner told a press conference: "What is correct, at the current time, what I have read, what I have heard, which seems exact, is that Neymar wants to come back to Barcelona". The PSG chief has already warned the Brazilian that he will no longer tolerate his "star" behaviour.
Spanish sports newspaper Diario Sport claims a five-year contract has been agreed.

Griezmann will not be guaranteed to walk into Barca's starting line-up, though, with Lionel Messi, Luis Suarez and either Philippe Coutinho or Ousmane Dembele usually making up their front three last term.
Any return for Neymar would likely require Barca to raise funds through sales.
Barcelona also introduced Frenkie de Jong, the 22-year-old midfielder who was signed from Ajax earlier this year for 75 million euros ($84 million).
"Atletico Madrid's response was obviously negative, as we believe that FC Barcelona and the player have disrespected Atletico Madrid and all its fans", the club said.
Paris Saint-Germain sporting director Leonardo has confirmed that Neymar can leave the capital club this summer if an offer that suits all parties arrives and that Barcelona have been in vague contact.
