However, in the 2017–18 season, Biseswar found himself in the substitute bench in a number of matches for the side. As a result, he was linked with a move away from PAOK, with Gençlerbirliği interested. But there was no offers made and Biseswar eventually stayed at the club. Biseswar then received a red card for a second bookable offence at the last minutes, as PAOK lost 1–0 against rivals, AEK Athens on 5 November 2017. After returning to the first team from suspension, he scored his first goal of the season on 19 December 2017, in a 5–1 win over Aiginiakos in the group stage of the Greek Football Cup. His return saw Biseswar regain his first team place back, under the new management of Răzvan Lucescu. His third goal of the season came on 28 February 2018, in the first leg semi-finals of the Greek Football Cup, in a 3–1 win over Panionios. Two months later, on 22 April 2018, Biseswar scored and set up one of the goals, in a 2–1 win over Xanthi. He later helped the side overcome AEK Athens to lift the Greek Cup at the Olympic Stadium in Athens after an enthralling final ended in a 2–0 win for the Salonica club, as PAOK retain Greek Cup to wreck AEK’s double dream.
