In the 2009–10 season, Biseswar found himself playing in the first team by coming on from the substitute bench. The decision to put Biseswar came from new manager Mario Been, who was frustrated with his mentality with the club. Despite this, he scored his first goal of the season in the second round of the KNVB Cup, in a 5–0 win over Harkemase Boys. Biseswar soon regained his first team place for the side, where he replaced Sekou Cissé, who suffered an injury and the one who dispatched Biseswar to the substitute bench. Biseswar continued to regain his first team place for the side throughout the 2009–10 season. Despite being sidelined on three occasions for the side during the 2009–10 season, Biseswar went on to make thirty–three appearances and scoring once in all competitions.
