Cape Town - Springbok coach Heyneke Meyer says their game plan was executed well for the first 60 minutes against Australia in Perth, before a few "soft" moments cost them dearly.The Boks lost 26-19, after squandering a 13-3 lead in the first half and the coach also admitted that mentally his players weren't up to the task."It is all about handling pressure, being mentally tough and showing character," he told the Times Live website.Meyer though insists that their kick-and-chase game plan was the right method to utilise."To win away from home you have to have a great game-plan and execute it. I thought we executed the game-plan well for the first 60 minutes. I thought we put them under pressure but we had two soft moments in the game that cost us and away from home you can't make those mistakes. There was a little bit of a lack of experience on the field," he said.The Boks now travel to New Zealand where a clash against the All Blacks in Dunedin awaits on Saturday.
