Premier Mark McGowan has labelled Perth Glory’s heart-stopping semifinal victory “one of the greatest games that anyone will ever see” as owner Tony Sage yesterday slammed the decision to shift his side to Optus Stadium for the A-League grand final next Sunday.

Glory downed Adelaide United in a sudden-death penalty shoot-out at HBF Park on Friday to make their first championship final in seven years, with Mr McGowan revealing he hugged Mr Sage after Joel Chianese kicked the decisive goal.

“I was sitting next to Tony Sage and he was, to be fair, pretty nervous,” Mr McGowan, who was at his first ever A-League game, said.

“I kept telling him it would be OK and we would win — admittedly I was publicly more confident that I was internally.

“We were all on the edges of our seats.

“It was one of the greatest games that anyone will ever see.”

Mr Sage joked yesterday that when the Premier was consoling him during the tense penalty shootout: “I was wondering what the hell I was listening to him for. He doesn’t know anything about football.”

A crowd of 17,868 — 12 more than this season’s previous record set against Melbourne Victory — watched Glory beat United.

While admitting hosting the final at Optus Stadium was good for the sport, with an expected 50,000-strong crowd double the capacity of HBF Park, Mr Sage said it was a cash grab and would cost his side home ground advantage.

“The FFA want to maximise revenue for themselves. They don’t care what the clubs think,” he said.

“I’m a traditionalist. I want our home ground advantage.

“Optus Stadium becomes a neutral ground. That’s the way I look at it. That's the way the whole of the football department looks at it.”
