Cape Town - Nick Mallett has given the Springboks advice on what areas need work as they prepare to face Wales in Durban this weekend.As it happened: Boks v World XVAfter a promising start, Mallett's World XV ran out of steam against the Boks at Newlands over the weekend, eventually losing 47-13.However, the World team fared well in the set pieces, and Mallett pointed to areas which the Boks should pay attention to this week."We (World XV) lost only one lineout ball, which is very uncommon for an invitational team that only had one practice session," Mallett told Die Burger's website."In the scrums we forced penalties in both the first and second half and at one stage we pushed the Boks back almost 10 metres."Those are aspects the Boks would want to work on."The Sharks front row of Jannie du Plessis, his brother Bismarck and Beast Mtawarira struggled and looked somewhat lethargic in their scrummaging, with New Zealander Carl Hayman and South Africans Craig Burden and Pat Cilliers notably impressive for the World XV.Bok coach Heyneke Meyer acknowledged that their scrummaging was below standard, but said he wasn't too worried. He pointed to the fact that they only had three training sessions and the front row had also dominated the Test arena last season.While Meyer is unlikely to change his starting front row, he did call up Cheetahs prop Trevor Nyakane into the squad ahead of Saturday's clash at Kings Park (17:05 kick-off).
