Sydney United 58 crowned 2016 National Premier Leagues champions

Glen Trifiro scored a hat-trick as Sydney United 58 secured the Australian second-tier title over Edgeworth FC

Sydney United 58 have become the first club to win the National Premier Leagues (NPL) Grand Final twice after knocking off Edgeworth FC 4-1.

The inaugural NPL champions from 2013 claimed their second title on Sunday with Glen Trifiro scoring a hat-trick at the Sydney United Sports Centre.

Sydney United set up their victory before the interval but Edgeworth pushed the hosts all the way in the second half, with Keigo Moriyasu scoring just before the hour mark to keep the Eagles in the second-tier grand final.

But Trifiro completed his hat-trick in the last 12 minutes left to wrap up victory for Sydney United.

The match started in a lively fashion with the visiting Eagles creating a couple of openings on the counterattack, while Sydney United's Pani Nikas hit the post with a free-kick in the 11th minute.

It was a portent of things to come, as Nikas opened the scoring six minutes later via another dead-ball opportunity.

The attacking midfielder added his sixth goal of the 2016 NPL Finals, blasting his free-kick into the wall and it deflected inside the right post of Jim Fogarty's goal.

Edgeworth thought they had equalised just before the half-hour mark when Sydney United goalkeeper Thomas Manos flapped at a corner and ex-Central Coast Mariners striker Daniel McBreen bundled the ball home.

But following consultation with his assistant, the referee ruled the goal out for handball against McBreen.

The hosts made it a double blow for Edgeworth in the 29th minute, with Trifiro volleying Chris Payne's knockdown past Fogarty.

Payne hit the post soon after, while the Eagles gained some ground late in the half with Moriyasu and McBreen sending attempts just wide.

That turn in momentum continued after the break as Moriyasu forced a good save from Manos, while the visitors got on the scoresheet in the 57th minute via the penalty spot.

A flowing move from Edgeworth eventually saw Moriyasu release Keanu Moore into the box and Sydney United captain Nick Stavroulakis hauled down the latter.

Moriyasu took responsibility for the penalty and although Manos saved his first effort, the Japanese forward followed up to tuck the rebound into the bottom corner.

Aaron McLoughlin missed a big opportunity to level the scores moments later.

But as Edgeworth pushed for an equaliser, Trifiro ended the contest with two late goals on the break.

In the 78th minute, Edgeworth lost possession in the centre circle and Trifiro surged forward to convert from the edge of the box, while 11 minutes later, the former Central Coast Mariners midfielder struck from Robbie Mileski's cut-back.
