Glory held their nerve in Saturday night’s grand final qualifier to win in a shootout after the two teams were locked 1-1.

The WA club booked their first ever A-League Grand Final appearance and will face a rampant Brisbane Roar on Sunday.

Burns said once the clash with the Mariners went into a shootout there was plenty of confidence, with a number of players putting their hands up.

That confidence was shown in five expertly taken penalties. The last one, by Burns himself.

“I will again, without a doubt,” he said when asked about the prospect of taking another pressure penalty in a grand final shootout.

“I’m full of confidence and you have to have that belief in yourself. It’s what’s carried us through thus far."

He added: “We’d practiced our penalties and knew each and every penalty taker and when they’d take their penalty.

“There was a lot of confidence surprisingly. It’s a tough way to win or to lose. But we were very confident.”

Burns said this week was a time to analyse the Roar’s game but not to forget a key ingredient in their success.

“We also have the belief. To have won the first three games in the finals is a tremendous confidence builder," he said.

“It’s going to be a game to savour and we’re going there for a result.”

Meanwhile, Burns said Central Coast coach Graham Arnold’s comments post match lacked a degree of humility.

Arnold pointed to refereeing decisions going against his “smaller” club, including Shane Smeltz’s first half equaliser, which replays showed might have been offside.

And while saying he didn’t feel bitter Arnold suggested he’d rather make the final 16 of the ACL than make an A-League grand final.

“Obviously Arnie’s disappointed. It’s a tough way to go out but I suppose you’ve got to be gracious in defeat and humble in your victories," said Burns.

“They are a class team but also you can’t take any credit away from us and what we’ve achieved.

“Super proud. It feels like a wonderful dream at the moment. We’re on cloud nine.”

And like his coach, Burns had a quiet word with owner Tony Sage who cut a jubilant figure at the end of the Saturday’s match.

“I’ll be hitting him up for some bonuses for the boys, hopefully,” he said with a laugh. “He was over the moon. And to finally get the team into a grand final was an honour.”
