Cristiana Girelli said she would be happy to keep playing the role of super sub after scoring an 87th-minute winner as Italy beat Argentina 1-0 in a feisty encounter at the Women's World Cup on Monday. It looked like Italy would have to settle for a draw in their Group G opener at Eden Park after Arianna Caruso and Valentina Giacinti both had goals disallowed in the first half. But Girelli, the Juventus veteran who was Italy's top scorer in qualifying, came on for 16-year-old Giulia Dragoni near the end and needed just four minutes to make her mark with a superb header.
