A pulsating contest which see-sawed constantly throughout was finally decided when Daniel Fogarty blasted home the winner just two minutes before the end of extra-time.

It sends the Futsalroos through to Saturday night’s final against Thailand, who beat the Aussies in the final of last year’s event.

But Robert Varela’s side will be confident of getting revenge after showing tremendous character to beat Vietnam.

The Aussies were on the back foot early on with Phung Trong Luan scoring on just seven minutes to give the Vietnamese a deserved early lead.

The setback seemed to fire-up the Futsalroos and they hit back just before the break when Jarrod Basger turned in Gregory Giovenali’s cross.

A pulsating second-half started with Fogarty putting the Aussies back in front only for Trong Luan to equalize just four minutes later.

But before the Vietnam players could settle down, Jordan Guerreiro sped down the right and released to Gionevali to put the Aussies ahead again.

It looked like that would be enough but in the final minute Vietnam skipper Nguyen BaoQuan capitalized on a power-play to smash in and equalizer and send the game to extra-time, where Fogarty scored his second to set up another crack at Thailand in the final for a second straight year.

“It will be a good rematch,” Australian coach Varela said.

“I know that Thailand have brought a younger squad but that does not mean that they are not any good.

“They are in the final, so we have to prepare well.”
