South Africa must beware one of their own when Graeme Smith’s power-packed team clashes with New Zealand in the World Cup quarter-final on Friday. Former pace spearhead Allan Donald, who claimed 330 Test and 272 one-day wickets for South Africa, will help to plot the Proteas downfall as New Zealand’s bowling coach. Donald, 44, who is working alongside coach John Wright, said he was delighted that the Black Caps were facing South Africa in the day-night match at the Sher-e-Bangla stadium. Donald reminded his former team that New Zealand have won three of their five World Cup meetings against them, including a five-wicket success in the Super Eights round of the 2007 edition.
