Those stresses did not appear to be getting to the star too much when he posted on Instagram to show off a new hairstyle, complete with dreadlocks, as he continues his recuperation in his homeland.

Brazil's first game at Russia 2018 is against Switzerland in Rostov on 18 June (AEST).

Neymar has scored 28 goals in 30 appearances across all competitions this season for PSG but his arrival for a world-record fee from Barcelona has since sparked regular rumours of dressing room unrest at the French giant.

Midfielder Adrien Rabiot sought to dismiss such talk over the weekend by posting an Instagram photo of Brazilian defender Marquinhos sharing a joke during training with himself, Presnel Kimpembe and Germany international Julian Draxler.

"A member of the 'Brazilian' clan was caught laughing with the 'French' clan!?" he wrote.

"Attention @marquinhosm5 [make sure] that it does not happen again!! Love you boys."

PSG travels to Nice on Monday (AEDT) and sits 14 points ahead of defending champion Monaco at the Ligue 1 summit.
