Developments at the Parc des Princes yesterday showed that Neymar and Mbappe ignored the conflict over penalty kick rights.
Neymar scored his eighth goal since the start of the season, including six in Ligue 1 and two in the French Super Cup win over Nantes 4-0, to retain one point for PSG.
Earlier, Kevin Volland quickly removed Presnel Kimpembe and finished off the opening corner in the 20th minute.
In this match, PSG hit the visitors’ wooden frame three times.
At the end of the first half, Messi hit the left post with his left foot and Mbappe smashed the other post.
In the 74th minute, it was Achraf Hakimi’s turn to fire a cannon from outside the penalty area to send the ball bouncing off the post and then all the way across the line.
PSG have scored 28 times in Ligue 1 since the start of last season, 12 more than any club in the same league.
Galtier said PSG did not play well in the first 35 minutes because of surprises with the intensity of monaco’s play and way of playing.
The 56-year-old coach praised his fiercely contested opponents, switching from defense to attack very quickly, like Volland’s opener.
But he said PSG played better in the second half and deserved to win.
“The beginning of the match will be a lesson for PSG to continue to improve,” Galtier stressed.
Held at the Parc des Princes, PSG remain at the top of Ligue 1 with 10 points, ahead of goal difference over Marseille and Lens.
