Paris Saint-Germain are understood to be worried about Neymar's parting during his return to Brazil.
The winger was given some time off over the winter break, and he chose to spend some of that back in his homeland. While he was there, he was filmed dancing on stage at a concert, drinking and playing football on an inflatable pitched covered in soapy water, which saw him slip over on to his back on a number of occasions.
While he is obviously allowed to do whatever he wants with his free time, PSG will likely be unhappy with one of their stars and most valuable assets risking injury by playing slip-and-slide football - especially since injuries have sidelined him for plenty of games already this year.
There is no mention of whether PSG plan to discuss the situation with Neymar, but he will almost certainly face fresh questions about his lifestyle away from football.
Back in March 2019, Neymar defended his behaviour to Globo Esporte, insisting that his performances on the pitch have nothing to do with how he chooses to spend his personal time.
"I do not think that my social life hinders my performance on the pitch," he said. "In fact, I even find it funny that what I do off the pitch gets compared with what I do on it.
"My statistics on the pitch are still very good. I said back during the  Olympics that 'my personal life is my personal life.' I will keep going, doing what I think I should do, because it is me - my business.
"On the pitch, I can be questioned - [journalists] are there to talk about my performances. You can talk about that. Away from the pitch, I will take care of myself. If I want to do it, I will do it - my life is mine."
This season, Neymar has bagged nine goals and six assists in his 12 appearances for PSG. Injuries may have disrupted his season so far, but he looks to be in a rich vein of form, contributing at least one goal and one assist in his last three league matches.
