The Australia national football team Socceroos pulled off a stunning 2-0 upset over Turkey in their World Cup Group D opener on Saturday. Coach Tony Popovic's bold selection gamble paid off as Nestory Irankunda and Connor Metcalfe scored the goals. Rookie goalkeeper Patrick Beach produced a string of crucial saves to help secure a famous Australian victory at Vancouver's BC Place Stadium. Australia coach Popovic had dropped experienced captain and goalkeeper Maty Ryan in favour of Beach, winning only his third cap. Vice-captain Jackson Irvine was also dropped in favour of 21-year-old midfielder Paul Okon-Engstler. Both selections proved to be inspired as Beach denied Turkey with fine saves and Okon-Engstler set up the opening goal. Turkey dominated possession but could not find a way past the Australian goalkeeper. One of Turkey's best chances came in the 27th minute when Real Madrid's Arda Guler forced a smart save from Beach. Just seconds after that chance, Australia took the lead as Okon-Engstler pumped the ball upfield for Irankunda to score. Irankunda celebrated by mimicking former Australia skipper Tim Cahill's signature goal celebration. Beach kept up his commanding form in the second half, turning a Guler free-kick wide for a corner. Australia made the game safe in the 75th minute when Metcalfe picked the ball up in midfield and shot home from 25 yards. The win leaves Australia level on three points with Group D leaders the United States. Australia will meet the United States in Seattle on Friday. The Socceroos' victory was a major shock as Turkey had arrived in North America dreaming of making a serious run in the knockout rounds. But the Australian team's well-organised line-up proved too strong for Turkey's talented team. Australia's next match will be crucial in determining their chances of progressing to the next round.
