After a summer of flux at the Parc des Princes filled with new arrivals and Lionel Messi's departure, it is the Mbappe stand-off that continues to dominate the headlines.
The France captain has refused to sign an extension to his PSG deal, meaning he can leave for free next year, with Real Madrid long seen as his preferred destination. PSG want to sell him now and bring in a significant transfer fee for a player who cost 180 million euros ($198 million) from Monaco in 2017.
New coach Luis Enrique on Friday said he hoped a solution can be found, but Mbappe has not been allowed to train with the first team and was left out of the squad to face Lorient.
Instead he sat alongside fellow 2018 World Cup winner Ousmane Dembele, who completed his transfer from Barcelona earlier in the day, as Luis Enrique handed debuts to six players.
Goncalo Ramos started in a new-look attack with Marco Asensio and Lee Kang-in, while Milan Skriniar and Lucas Hernandez began in defence as Uruguayan Manuel Ugarte lined up in midfield.
