Excelsior Maassluis

The club's home ground is the 5,000 capacity arena known as Sportpark Dijkpolder.

[2] Also known as the Tricolores, Excelsior due to their 2016 title win, was promoted to the Tweede Divisie.

As so in the division's inaugural season Excelsior ended up at fifth in the league's standings.

However, Excelsior defeated USV Hercules 4–1 on aggregate in the first round, Harkemase Boys 3–2 in the second round, and then defeated SC Genemuiden 6–1 in the final, retaining their Tweede Divisie status.
