Perth Glory fans may have a tough call to make next month - or maybe not.

Do they watch their side play in the A-League grand final or stay at home and wait for the Federal election result?

If Glory end up facing Sydney FC then the game will be played on May 18 - at Optus Stadium if Glory host it - to accommodate Sydney's Asian Champions League commitments.

If they play any other side it will be the next day.

Kick off on either day is expected to be late afternoon or early evening but FFA have not yet made a decision.

Glory ended their 15-year silverware drought on Sunday night, claiming the A-League Premiers' Plate with the 1-0 win over Newcastle Jets at HBF Park.

Ivan Franjic's 65th minute goal sent fans and owner Tony Sage into raptures as coach Tony Popovic earned the title in a remarkable first season in charge.

Sage admitted to being a "little dusty" today after a night of celebrations and also admitted dropping the trophy on the pitch after the presentation to captain Diego Castro.

"The vision has been fulfilled a year earlier than what we expected," Sage said.

But he also said there was unfinished business with the finals series ahead and planning for the Asian Champions League.

"Nobody's counting their chickens," Sage said.

"We're up for the challenge. Popa is driven, I'm driven, the players are driven.

"It's only going to be a feather everyone's cap if we can do it

"Asia has been a dream of mine from day one. It's going to be huge."

Sage was also handed another first, the opportunity to address the players in the change room after the game.

"It was fantastic," he said.

"Popa asked me to give a speech to the players. I've never done that before. I was gobsmacked.

"It was a very emotional time. I shed a few tears. I think a few people did. It's been a lot of hard work from a lot of good people."

He said it had been important for Glory, with an unassailable eight-point lead with two rounds remaining, to be presented with the trophy on Sunday night.

They still have to play second-placed Sydney FC on Thursday followed by Wellington Phoenix 10 days later at HBF Park.

"It would have been ridiculous to know we had won and for the players not to be able to celebrate," Sage said.

"Not one fan left, maybe the three Newcastle fans.

"That's the first time I've been at the club where they all stayed right to the end. That was fantastic."
