"I'm still about a month away", he said, as quoted by the official Ligue 1 website.
Neymar, 26, hasn't played since sustaining the injury in a February 25 clash with rival Marseille, and PSG manager Unai Emery hopes the dynamic Brazilian will be fit to play for the club again this season.
However, PSG submitted to Real's supremacy in the last 16 of the Champions League, and there have been rumours about Neymar not being happy at the Parc des Princes. When Neymar gets here, he'll be very eager to play.
PSG coach Emery Unai said earlier Friday that Neymar was "close" to returning to the club. Having won the league in three successive seasons, Les Parisiens were previous year dethroned by Leonardo Jardim's team.
PSG could wrest the Ligue 1 Conforama title back from AS Monaco with victory over the principality side this Sunday, and although Neymar won't be there to watch proceedings, he is expected back soon.
"The speed of his recovery in the next 10 days will allow the right date to be set for a return to training without any restrictions", was all PSG were willing to say in a statement.
PSG star Neymar has revealed that he will be ready to star for Brazil at the World Cup - and expects to be out for just one more month.
Brazil will also face Costa Rica and Serbia in their group, as they target winning a sixth World Cup, four years after the nightmare of their 7-1 loss to Germany in the semi-finals on home soil.
