Paris Saint-Germain have lashed out at reports of a fight between Neymar and Julian Draxler.
French newspaper Le Parisien then reported that Neymar and Draxler came to blows when the German accused his team-mate of being selfish on the pitch after the following 3-2 loss to Montpellier.
The Brazilian star reportedly said: "Who are you to talk to me like that? The only thing you know how to do is pass the back ball back."
It is claimed Tuchel and PSG sporting director Antero Henrique then had to separate the pair, and that Neymar had previously accused the club's younger players of ignoring the more experienced squad members.
But the club has refuted the accusations of a rift involving Neymar.
PSG tweeted on Wednesday: "Strange game from Le Parisien: presenting Neymar, a phenomenon of world football, as a player who fights with his teammates in the locker room. How can you invent such things? Were you in the locker room?"
Paris have now won just one of their last seven games in a significant slump at the end of the season.
They have already been crowned Ligue 1 champions and hold a 16-point lead over second-place Lille, but look set to end the campaign on a sour note unless they can turn things round in their three remaining games.
Despite winning every domestic trophy on offer in 2017-18, PSG have failed to win a cup competition this term.
With Adrien Rabiot looking likely to depart to Barcelona on a free transfer this summer, the Parisians could look to bolster their squad in the summer transfer window.
