At the start of the 2014–15 season, Van der Wiel played the entire match in the Trophée des Champions, a 2–0 PSG win over Guingamp. After Christophe Jallet's transfer to Lyon, Van der Wiel continued to feature at right-back, although he faced a new competition from new signings Serge Aurier and Jordan Ikoko, which often forced him to the substitutes' bench. By season's end, Van der Wiel helped PSG win the domestic treble: Ligue 1, Coupe de France and the Coupe de la Ligue.
