Mbappe is out of contract at the Parc des Princes in June with question marks over his future
There is said to be growing discontent within the PSG squad that a number of star players are privileged at the club – who are said to protect them publicly and encourage such behaviour due to their lack of action.
There is said to be a South American clique within the dressing room – led by Neymar and Messi but which includes Paredes, Marquinhos, and Angel di Maria, while there is a separate group of French speaking players.
The latter are said to be led in seniority by Achraf Hakimi alongside Mbappe, who is reported to be less close with the South American group than in previous seasons.
The future of Mbappe generally is coming under great scrutiny as he is out of contract at the end of the season and has been free to open pre-contract negotiations with clubs outside of France from this month.
Things have not clicked between Mbappe and Messi for PSG this campaign
Mbappe has recently hinted at a move to Real Madrid and his most recent interview suggested that he is open to a move away from Paris, where he is out of contract this summer.
His comments after netting a hat-trick in the win at Vannes have now come under scrutiny from PSG website BUT PSG, who cite L’Equipe in terms of the problems behind the scenes.
Mbappe said after the victory: "It was not an easy match to play but we were here to play the game."
Those pointed comments appeared to be aimed at those players who were not involved – notably the South American contingent.
Pochettino is said to be aware of the problems and believes that problems off the pitch are eclipsing concerns on the pitch, despite PSG holding a double digits points lead at the top of Ligue 1.
Mbappe has bagged 18 goals in 26 appearances this term – his attacking output far exceeding that of his fellow attacking teammates Messi and Neymar.
PSG face a season-defining Champions League Round of 16 tie against Real Madrid next month and Pochettino will hope to resolve issues ahead of that clash.
