The Brazilian left the La Liga giants for the Ligue 1 side in a stunning €222million deal last summer.
He has endured a mixed start to life at the Ligue 1 outfit.
Neymar has scored 10 goals in 11 games, but also fell out with strike partner Edinson Cavani. The 25-year-old was sent off in their 2-2 draw with Marseille and there are suggestions he is also unhappy with manager Unai Emery’s tactics.
“La Porteria understands that the Brazilian regrets having left Barça and misses his life in Barcelona.
“The player is unhappy with Emery and his methods. The player’s environment does not feel comfortable in Paris either,” Catalan TV station, La Porteria, tweeted on Monday.
