VIDEO: Kylian Mbappe is chilling! PSG forward changes out of kit to greet public and takes selfies after half-time substitution - rather than rejoin bench - in bizarre scenes during Monaco clash

PSG coach Luis Enrique opted to take the forward off after a disappointing 45 minutes into the Ligue 1 clash at Monaco. There were fears that the attacker had picked up an injury, but his casual stroll through the tunnel and along the side of the pitch suggested that he was substituted for a different reason.

Mbappe opted against joining his fellow PSG stars on the bench. Instead, he greeted supporters and took a picture them before walking up the stairs and joining his mother in the stand, where he sat smiling and talking.

After being substituted for the second time in a row, tension may be rising between Mbappe, his team-mates and coach Luis Enrique. The France star has already informed the club that he will leave at the end of the season in a free transfer and looks set to join Real Madrid in the summer. Before then, though, the 25-year-old will hope to be back in the team when they take on Real Sociedad in the Champions League on Tuesday.
