An incredibly enteraining 2016 NPL SA Season draws to a close this Saturday - but not without the State's top two battling once more.

Campbelltown City responded from three straight losses with an impressive 4-0 win over West Torrens Birkalla to set up the third instalment of the Joe Mullen vs. Damian Mori clash of this season's Finals Series.

Having beaten Campbelltown in both legs of their Major Semi-Final last month, Adelaide City will rightly go in as favourites to complete the Premiers-Champions Double but they'll have to be at their absolute best.

This clash kicks off at Coopers Stadium from 3pm on Saturday afternoon.

The penultimate game of the 2016 Senior Men's Season is the State League 1 Grand Final between Cumberland United and Para Hills Knights.

The pair are extremely familiar opponents, having met in the final round of the season, and a two-legged Major Semi-Final last month.

There's scarcely a difference between the two sides and although they're both promoted to the 2017 National Premier League - they'll both be desperate to finish the season as Champions. 

This contest gets underway at 12pm.

The first game of the bumper day of football action is the NPL Reserves Grand Final, featuring Premiers MetroStars and West Adelaide - the latter attempting to become Champions following a fourth placed finish during the regular season. 

Entry to Coopers Stadium is priced at $10 for Adults, $5 for Concession and FREE for Under 16's.

On Sunday at Elite Systems Football Centre, the NPL Under 18's and State League 1 Reserves and Under 18 Grand Final's will be contested.
