The World Cup's leading points scorer, South African pivot Morné Steyn, has already achieved a 100 percent success rate twice in the tournament. Yet, there is room for improvement.

This, according to former Springbok points machine Braam van Straaten, will require only minor 'tweaks' to his technique.

Van Straaten, who is heading to New Zealand next week to join up with the Wallaby camp ahead of their World Cup quarterfinal and other possible play-off matches, raved about Steyn's feats at the 2011 edition of the global showpiece - currently being staged in New Zealand.

Steyn - who achieved a 100 percent strike rate in the Bok victories over Wales and Namibia, as well as a 72.7 percent success rate against Fiji - has collected 48 points in his three matches.

He scored two tries, 13 conversions and four penalties.

Tongan sharpshooter Kurt Morath is a distant second - 31 points after three matches, followed by French ace Morgan Parra with 28 points in two matches.

Van Straaten told this website in an exclusive interview, ahead of his departure to New Zealand next Monday, that Steyn has proved his worth as a goal-kicker over-and-over on the international stage.

"However, Morné still has a few minor errors in his armour ... I won't say that too loudly," Van Straaten said.

"If, one day, I could just stand close to him and whisper to him - I'll tell him how to eliminate those minor errors."

Van Straaten, a 21-Test Bok who scored 221 points (294 points in all matches, including tour matches), sung the praises of the current Bok No.10.

"He [Steyn] has proved time and again - in every competition he has played in - that he is an outstanding goal-kicker with a great trajectory and technique.

"Despite the fact that he has some minor flaws, he is still an outstanding kicker."

Asked if it is Steyn's big match temperament that makes him so successful, Van Straaten said hard work also plays a big role.

"I have always said, talent only takes you up to a certain stage, and when you get under pressure you return to technique and then those natural talents can fall away a little.

"If your technique is very good, compact and you don't commit any errors in your approach to the ball, then you will be successful."
