Following his loan spell at Toulouse came to an end, Chantôme made his first appearance of the 2014–15 season for Paris Saint-Germain, coming on as a 71st-minute substitute, in a 2–0 win against Guingamp in the Trophée des Champions. Throughout August, his future became uncertain, as many clubs, including Toulouse were interesting signing him but ended up staying at the club. However, his first team opportunities became limited once again at Paris Saint-Germain, which saw him placed on the substitute bench. As a result, he was restricted to twelve appearances for the club this season. This led to further speculation over his future at Paris Saint-Germain when the transfer window opens in January. Amid to the transfer speculation, he made his last appearance for the club on 5 January 2015, in a 3–0 win against Montpellier in the first round of the Coupe de France.
