PSG superstar Kylian Mbappe has been warned by coach Thomas Tuchel that he needs to recognise that he is part of a team after the France international was visibly upset to be substituted during the 5-0 Ligue 1 win over Montpellier on Saturday.
Mbappe, 21, was substituted after 68 minutes after scoring PSG's fourth of five goals just 10 minutes earlier.
The former Monaco man and Tuchel were locked in conversation as the change was made as part of a double substitution that saw opening scorer Pablo Sarabia also withdrawn and Mauro Icardi, as well as Edinson Cavani, sent on.
Speaking after the match with Canal+, Tuchel urged Mbappe to recognise that he is part of a team.
"Handling dressing room egos is demanding," said the German. "Not difficult but demanding. It is not good, nor was it going too far. We are a team and that must be respected.
"I am coach. Somebody has to decide who comes off and goes on. These are not good images as they negatively affect the state of mind. We are playing football -- not tennis. Kylian is intelligent and has a good mentality, so we do not need this sort of situation.
"It is not good as it opens discussion and distracting subjects that affect our spirit. Together, with Kylian, we have shown a very professional and concentrated spirit. This topic always gives the impression that it is not like that, which is a shame. I am not angry, just sad as it was unnecessary."
Also quizzed about Neymar's early birthday celebrations planned for Sunday, Tuchel admitted that he was not thrilled about the idea two days ahead of their match with Nantes.
"Sunday is not good [for Neymar's birthday party]," he said. "However, I am neither his father, nor handler, nor agent -- I am just his coach.
"I will not say if I am going [to Neymar's party] or not. You can wait until Sunday. It is off-topic. Neymar's night is a distraction, obviously, and I always protect my players. I love them lots and prefer to talk internally. If there are hard truths to be said, I prefer to do it internally."
Neymar, who teed up Mbappe's goal and was booked by the referee late in the first half as tempers flared because of the Brazil international's use of skill, revealed via Instagram post-match that he and Leandro Paredes had signed a PSG shirt for Andy Delort.
The Montpellier attacker was vocal in his criticism of both players in the build-up to the match after a heated meeting towards the end of 2019, declaring that "at least Zlatan [Ibrahimovic] was very respectful" during their clashes.
