Neymar told a TV Globo variety show on Sunday that he feels no pain, but he can not put his injured foot on the ground without an orthopedic shoe.
Speaking to Brazilian television channel TV Globo, Neymar said: "I need about a month, but it is healing well".
PSG, who netted four goals in the opening half-hour, have 87 points with five games remaining and lead second-placed Monaco by 17 points after doubles by Giovani Lo Celso and Angel Di Maria, goals by Edison Cavani and Julian Draxler and a Radamel Falcao own goal.
Paris Saint-Germain reclaimed the Ligue 1 title this evening courtesy of a 7-1 drubbing of league rivals Monaco at the Parc des Princes. "Perhaps he'll have time to play a few matches before the end of the season", Emery said.

PSG's first-choice attackers have unsurprisingly been crucial to them running away with the league, with Neymar transitioning seamlessly after his world-record EUR222million switch from Barcelona, scoring 19 and setting up 13 in 20 Ligue 1 games before fracturing a metatarsal in February.
That prognosis appeared to cast doubt over whether Neymar would be fit in time for the World Cup in Russian Federation, which begins on June 14.
