Original retro vintage football shirt RBC 2017/21

In the 2017-2018 season, RBC Roosendaal played in the Sunday Third Class A (South 1) of amateur football, following promotion the previous year. It was a season of two halves in which the club impressively bounced back and ultimately competed for promotion. Head Coach: The squad was led by coach Danny Mathijssen this season. Club Top Scorer: Forward Anwar Tarfit became the club's top scorer with 16 goals in the league. Home Ground: Home matches were played unchanged at the Herstaco Stadium in Roosendaal.

In the 2018-2019 season, the first team of RBC Roosendaal played in the Sunday 3rd Class A (District South 1) of amateur football. It was an extremely eventful and turbulent season in which the club missed out on the championship and promotion due to penalties and coaching changes. Under the leadership of Head Coach Henk Vos, RBC competed for the top spots and the championship for an extended period. During the season, an abandoned match against vv Steenbergen led to severe sanctions and a points deduction from the KNVB. This penalty ultimately cost RBC the direct national title in the 3rd Class. In the final phase of the season, Henk Vos was replaced by the new coach Koos Waslander.

During the 2019-2020 season, the first team of RBC Roosendaal competed in the Sunday 3rd Class A (District South 1) of Dutch amateur football. RBC Roosendaal held a strong lead in the 3rd Class A throughout the season. The team recorded strong victories, including a 5-1 win against VV Zundert, a 1-0 victory in the derby against SC Gastel, and a 1-2 away win at MOC'17. The season was prematurely halted in March 2020 due to the outbreak of the COVID-19 pandemic. No Champion, But Promotion: The KNVB decided not to name any official champions for this season. RBC's 2020-2021 season in the Tweede Klasse E (Zuid 1) was definitively halted after only four matches due to the coronavirus pandemic. Under the leadership of trainer-coach Koos Waslander, the first team played a very short but high-scoring season in which the club ultimately finished in fifth place with 6 points. One of the few sporting highlights of the competition was the won city derby against rival neighbouring team RKVV Roosendaal, which ended in a high-scoring 2-5 victory for RBC.
