Bognor manager Jack Pearce says his team are playing for their futures at the club.
The Rocks marked their last premier division home game of the season with a 2-0 win against Hitchin Town.
Top scorer Matt Russell scored a goal either side of half time to bring his tally to 23 this season.
Victory came four days after Bognor secured a place in the Conference south division next season.
Pearce said: "We have to strengthen to survive next season so there will need to be changes. I have a fair idea who is good enough and who is not."
