No one is more surprised at Massimo Luongo's standout Asian Cup performances than, well, the player himself as he prepares for the match of his life in Saturday's final. The young Socceroo plies his trade for third-tier English side Swindon Town, but after a head-spinning few weeks he is set to play in front of 80,000 fans in Sydney. Luongo's selection for Australia's opener against Kuwait was not expected, but he has proved indispensable, starting every game since and providing a tournament-leading four assists. To be fair I've only been tested at League One level, so it is nice to be able to do it on such a big stage Massimo Luongo "It's not what I expected on a personal level," said Luongo, man-of-the-match in Tuesday's 2-0 semi-final win over United Arab Emirates after setting up both of Australia's goals. "I'm a little bit surprised by my performances so far, but I know myself what I am capable of." Luongo is more used to playing at the likes of Yeovil Town's Huish Park or Scunthorpe's Glanford Park, where fewer than 10,000 go through the turnstiles. But he appears unfazed at performing in front of packed crowds at giant stadiums. "To be fair I've only been tested at League One level, so it is nice to be able to do it on such a big stage," Luongo said. "I'm just enjoying the whole thing," said the Sydney-born player. "If you're not enjoying it, then you shouldn't be doing it and I always enjoy it." Saturday's clash against the undefeated Koreans, who beat Australia 1-0 in group A, will be the Socceroos' sixth game in three weeks and Luongo said he was running on adrenaline. "I think I'm more overwhelmed than worried about how tired I am mentally," he admitted. Australia coach Ange Postecoglou has been rebuilding after the disbanding of Australia's "golden generation" and Luongo is leading the way. Despite the rotation to keep players fresh, Luongo has remained ever present. "It seems like every game he's becoming more and more confident. He's been a fantastic bonus for us," Postecoglou said. Luongo's performances have not gone unnoticed, with Spanish side Sevilla and English Championship teams interested.
