Reuser began his career at Dutch club Ajax and, having joined at youth level, made the step up to play in the first team. He was a skilful, goal-scoring midfielder who looked capable of being a permanent fixture in the Dutch national setup. His career was looking very promising, but he suffered a serious knee injury, which appeared to end his Ajax career. He moved to another Dutch side, Vitesse Arnhem. It was here that Reuser made his one and only international appearance against Ghana in a friendly. He did not really hit it off at Vitesse and was re-signed by Ajax. He made only one appearance for the first team and he was loaned to English club Ipswich Town in the 1999–2000 season after being scouted by Romeo Zondervan. Having scored a late winner on his début against Fulham and a memorable goal to seal off Ipswich's play-off win against Barnsley at Wembley, Ipswich signed him on a permanent basis. During his four-year stay at Portman Road he established a reputation as a free-kick taker. He was troubled by injury problems during his Ipswich Town career. Despite this, he managed to score 6 goals in his first full season with the club, establishing himself as one of the most dangerous attacking midfielders in the Premier League, helping Ipswich to an impressive fifth-place finish in the 2000-2001 season and a return for the club to UEFA Cup football. After that, however, the injuries really set in. Ipswich were relegated the following season and he also fell out with new manager Joe Royle. Reuser left Ipswich and joined Willem II for the 2004–2005 season. He was less troubled by injury in the Netherlands, but he missed two months of the season with Achilles tendon problems. He was still the club's top scorer as the team finished 11th in the table. The following season was more difficult for Willem II. Reuser spent a lot of the season on the sidelines, and the side finished 16th in the table, which meant play-offs again for Reuser. He saved his side, with a hat-trick in their semi-final against FC Zwolle. Reuser signed for another Dutch side RKC Waalwijk for the 2006–2007 season. He played for NAC Breda in the 2009–10 season. In January 2012, Reuser was linked with a return to former club Ipswich Town.
