Cape Town - Springbok flyhalf Johan Goosen says they let themselves down by allowing the game against Australia to slip through their fingers.The Boks lost the Test 26-19 in Perth, after squandering a 13-3 lead in the first half.Goosen, 20, said while he was immensely proud to become a Springbok, his feelings afterwards were mixed."It's sad we couldn't pull this one through. We set high standards as a team. There's no doubt that we should have won this one, so we're pretty disappointed," he told Beeld.Goosen was on the field for only 10 minutes but he showed enough in that time that he could flourish at international level.The Free Stater had a few line breaks which split the Wallaby defence open and his introduction to the team seemed to give the Springbok backline more urgency and direction. This will just add to the pressure on incumbent flyhalf Morné Steyn, who again struggled to give the backline any flow and direction.The Boks now travel to New Zealand where a clash against the All Blacks in Dunedin awaits on Saturday.
