UPDATED: SYDNEY Olympic coach Grant Lee was left dumbfounded after Perth Glory sensationally abandoned their preseason friendly match at the last minute.

The game was scheduled to take place at Belmore Sports Ground on Wednesday night, but Perth left the stadium an hour before kickoff without offering an adequate explanation to the National Premier League NSW club.

A tweet from the Glory’s official account apologised for the inconvenience, adding that the game was cancelled “due to unforeseen circumstances”.

But Lee, speaking to Radio 6PR in Perth, said he was still trying to work out what happened.

“I have no idea what the unforeseen circumstances are to be honest, it’s got me a bit baffled,” he said.

“Thirty-five years in professional football and I haven’t seen anything like this.

“They’ve turned up tonight, I believe there might have been a few hiccups during the week with their itinerary, but they’ve turned up tonight and they’ve just walked out.”

Glory was scheduled to warm up behind the goals as Olympic’s U16s were preparing to play a curtain raiser against South Coast Wolves.

Perth coach Kenny Lowe told 6PR that he made the decision to pull out of the game.

“Unfortunately, we couldn’t prepare correctly to play the game,” he said.

“We had no changing rooms (and) no warm-up area. I made a professional decision that if we can’t prepare correctly for a game, we’re not going to play the game.”

But Lee says Perth would have been well aware of the arrangements.

“The U16s were out on the park warming up and from what I can understand they weren’t happy that the U16s were about to play a game,” he said.

“We had arranged it, it had been promoted that way and they were well aware prior to the event that was going to be a curtain raiser. Part of the agreement between the two clubs was we thought it would be nice if they had a look at our juniors and promote the game. But then they said they needed the whole pitch to warm up.”

Fans had already begun to arrive and Olympic had organised corporate catering for the event.

Lee says he had a brief word with Lowe before the team left the stadium, who said to him: “The players’ heads aren’t there, they’re not right and I’m really sorry but we can’t play the game.”

Olympic held a training session at the ground instead.
