The beleaguered Springboks have to believe they can win as they face their next challenge this weekend. Bok coach, Heyneke Meyer, speaking at a media conference on Monday, said he believes the squad did their best despite going down 26-19 to Australia in Perth this past weekend in the Rugby Championship. He said, however, they will have to have a winning mind-set as they prepare for another tough match at the end of the week against the mighty All Blacks.
