Barca have agreed personal terms with the young Brazilian, but negotiations with PSG stalled over the weekend.
"I have a contract with PSG. My future will be decided by the club, but today everything seems to point to me continuing, although it is not for me to decide," remarked Marquinhos.
Sport says Barca chief Raul Sanllehí has been driving the deal, but no breakthrough is expected until president Josep Maria Bartomeu meets with PSG counterpart Nasser Al-Khelaifi.
Such a summit could be held in the coming days in Brazil during the World Cup.
