Kylian Mbappe and <a href="https://www.thenationalnews.com/tags/neymar/" target="_blank">Neymar </a>were enjoying themselves on Friday as <a href="https://www.thenationalnews.com/tags/paris-saint-germain/" target="_blank">Paris Saint-Germain</a> prepared for Saturday's match against relegation battlers Saint-Etienne. The mood was relaxed in Ligue 1 leaders PSG's training camp despite their shock 3-1 defeat at Nantes on Sunday. Randal Kolo Muani gave the hosts an early lead before Lionel Messi was denied an equaliser by a fine save from Alban Lafont. Nantes doubled their lead through a fine strike by Quentin Merlin in the 16th minute. Referee Mikael Lesage initially did not award a penalty for handball by Georginio Wijnaldum in stoppage time, only to take another look and point to the spot, with Ludovic Blas converting. Neymar reduced the deficit just a couple of minutes after the restart when played in by Messi, but then saw his soft penalty saved after <a href="https://www.thenationalnews.com/tags/kylian-mbappe/" target="_blank">Mbappe </a>had been brought down. Even so, PSG will not be too worried as they remain 13 points clear of Marseille, who host Clermont on Sunday, after a first league defeat since early October while Nantes move to fifth. On Saturday, Neymar could make his first start for PSG after two substitute appearances since recovering from a sprained left ankle. His team's loss at Nantes exposed flaws in midfield and defense that have been covered by Mbappe’s goals in several games. It was Mbappe, after all, <a href="https://www.thenationalnews.com/sport/football/2022/02/16/mbappe-scores-after-messi-misses-penalty-as-psg-beat-real-madrid-in-champions-league/" target="_blank">who won them the Champions League round of 16 first leg</a> against Real Madrid in stoppage time.
