In the 80th minute of the Ligue 1 clash, Ferland Mendy grabbed and took down Mbappe, handing PSG a penalty and the opportunity to double their lead.
Cavani took control and proceeded to walk to the spot. Neymar, however, had other ideas and approached his strike partner in an attempt to take over responsibility.
The Uruguayan was having none of it and can be seen raising his head with a condescending gesture, ultimately denying the request.
Neymar, disappointed, took a step back and watched as Cavani rifled to Lopes' right, but the Lyon goalkeeper was ready to spoil the party and expertly stopped the powerful drive.
Take a look at how the events unfolded here:
