Sydney FC coach John Kosmina said he was "grateful" the A-League match with Central Coast was postponed because it gave his men a much-needed rest after the David Beckham extravaganza.

Had the game gone ahead at Gosford's Bluetongue Stadium on Saturday night, it would have been Sydney's third fixture in six days, including the exhibition with Beckham's LA Galaxy last Tuesday.

"In hindsight, I'm grateful for the rest," Kosmina said.

"Everyone has been involved in the Beckham game, obviously, and there were guys that had to back up from the weekend before.

"Given the couple of niggles we've got as well with Juninho and Stevie Corica, the week off - or the extra few days off - will do us the world of good."

Referee Matthew Breeze called off the game moments before the scheduled 7pm (AEDT) kick-off due to a water-logged pitch.

The match is now likely to be played on the night of Friday, December 21 - a weekend where no A-League games were scheduled to allow for a Christmas break.

Mariners executive chairman Lyall Gorman said he would be requesting that date when he puts his submission to Football Federation Australia on Monday morning, and Kosmina and Sydney chief executive George Perry both agreed the 21st was the logical option.

"It makes sense to play it that weekend. We had a game scheduled for that night anyway - an internal trial," said Kosmina.

"I'm quite happy to play that game then to give us some continuity in the lead-up to the Adelaide game the week after."

With top four sides Newcastle Jets and Adelaide United both picking up maximum points on the road this weekend, the pressure is on Sydney to end their string of three-straight draws and start winning.

"We need points. Simple as that," said Kosmina.

"With Adelaide and Newcastle both picking up points, it opens up a bit of a gap.

"And considering we play Newcastle next week, we need results."

An injury-time header from Joel Griffiths gave the Jets a 1-0 win over Queensland Roar on Friday night, while goals from Paul Agostino and Lucas Pantelis saw Adelaide beat Wellington Phoenix 2-1.

At Members Equity Stadium, a brace to 20-year-old striker Nikita Rukavytsya helped Perth Glory to a 3-1 win over struggling champions Melbourne Victory for their first home win in more than a year.

Jamie Harnwell also netted for the Glory, while Adrian Caceres was the lone scorer for Melbourne, who moved to six games without a win for the first time in the club's history.

The results see the Mariners, who have a game in hand, remain on top on 27 points with a four point gap to Queensland Roar (23).

Adelaide United (22) are third with a superior goal difference to Newcastle Jets (22), and Sydney FC (18) are a further four points behind, but also with a game in hand.

Melbourne (16) are in deep trouble, drifting to six points outside the top four with only six games remaining, while Perth's win sees them move off the bottom of the table, ahead of Wellington on goal difference with both clubs on 13 points.
