The Springboks believe they can still win the Tri-Nations title, but Harry Viljoen and his charges are acutely aware of the fact that it is going to take a massive attacking effort on Saturday against the All Blacks if they want to achieve their goal.

The Boks need to score four tries in a victory in Auckland and then hope for a favourable result for them when the All Blacks and the Wallabies battle it out in the final Tri-Nations game on September 1. Coach Harry Viljoen promised that his team would go flat-out on Saturday in their quest for four tries.

"We can still win the Tri-Nations, but we must get a bonus point (with a victory)," said Viljoen. That will give the Boks 11 points and will put the defending champions, the Wallabies, under huge pressure as they would also have to beat the All Blacks and get a bonus point to retain the title.

South Africa have scored only two tries in their three games thus far and it will take a huge step-up in their attacking play if they want to score four tries against an All Black side renowned for its great defence. With game-breaking centre Robbie Fleck on crutches after injuring an ankle early in Saturday's draw against the Wallabies the Springboks lacked bite on the attack.

Fleck was confident that he will be ready to tackle the All Blacks, but his chances are slim of recovering in time. The Springboks could be looking to Andre Snyman to bolster their attack, but Deon Kayser has done nothing wrong when he replaced Fleck on Saturday. In fact, Kayser's solid tackling played a huge role in the Boks performance.

Snyman made his comeback this year after a two-season absence from the game because of serious ankle injuries. He made a limited number of appearances in the Super 12, but must still recapture the form that made him one of the world's best outside centres in 1997 and 1998.

Viljoen is obviously proud of the Springboks defensive record, but said it was now vital that they improve their attack. "We're starting to get it right on defence, but not on attack," he said. "We must not become a defensive team. We must become an attacking side."

Teams are currently struggling to breach the well worked out defensive lines and if this trend continues in the Tri-Nations, the Boks will struggle to achieve their goal of four tries. "Rugby is going to become very specialised and if you don't take on the challenge of beating those defensive walls you're not going to make it," Viljoen said.

"I think defence at this stage is ahead of attack, but attack will get there. We must make lifting our attack our challenge.

"We have to be a lot more efficient with the ball in hand and getting our forwards more aggressively into play. The cohesion between forwards and backs is where we are lacking. We're not testing the opposing defence enough. We're not keeping the ball and lack the patience. We need to build those skills."
