Paris Saint-Germain are said to be frustrated with Neymar over his trip to the Monaco Grand Prix.
The Brazilian joined some famous faces such as Maria Sharapova, Kylie Minogue and Tom Holland – who were also present at the event.
He posed for photos with celebrities in attendance and Formula 1 drivers as his PSG team-mates celebrated the Ligue 1 title.
Neymar has been injured since February but he is a prominent figure in the dressing room.
And his decision to enjoy a day in F1 has been seen as a provocative gesture by PSG, according to L’Equipe.
The 31-year-old forward even took part in Barcelona’s La Liga victory celebrations – raising more questions within the club.
It comes amid reports the striker could leave this summer, with four Premier League clubs reportedly interested in the superstar.
Newcastle are believed to be one of the teams chasing his move with the Toon eyeing several Galaticos.
PSG are reportedly ready to accept bids for Neymar, with SunSport revealing Manchester United could make a move.
But this can only happen if potential owner Sheikh Jassim takes over the club.
The French champions admit that Lionel Messi could also leave in the summer when his contract expires.
The World Cup winner was also absent from PSG’s title celebrations with the forward heading to the Coldplay concert in Barcelona.
