Thatcham Town complete their Hellenic Premier season away to Brackley Town Saints on Saturday having already secured fourth place in the standings.
Thame United were crowned champions this weekend after thrashing bottom side Henley Town 9-0, while rivals Bracknell Town slipped up against Highworth.
It has been a close contest between the two sides in the second half of the season, after Thatcham fell away despite having topped the table in the early stages.
They are sat on 67 points, six behind Flackwell Heath and three ahead of Ardley United, who have both played all of their games.
It means it will be another year in the Hellenic for the Kingfishers, following on from ending runners-up to Kidlington in 2015/16.
Saturday’s match starts at 3pm.
