Neymar returned to his native Brazil with his club's permission before France went into a mandatory lockdown due to the coronavirus pandemic on March 17.
"Not knowing when I can return [to play] gives me anxiety," Neymar published on his official website. "I really miss playing, competing, to be in the club environment with my PSG teammates.
"I really miss football. I'm sure the fans also wants to see everyone back on the pitch as soon as possible. I hope the decision comes out as soon as possible."
Two days later, French football's top two leagues were suspended indefinitely due to the global outbreak.
France's Professional Football League [LFP] has outlined plans for Ligue 1 and Ligue 2 to resume on June 17 with the aim of completing the 2019-20 campaign by July 25.

"I'm happy to train with Rica [Rosa] and with Neymar," Lima said. "The two are high level professionals and it certainly will also help me to return to play with a good rhythm."
