South Africa captain AB de Villiers insisted his side will not choke when they try to end their World Cup knockout misery in a Sydney quarter-final with Sri Lanka. The Proteas have never won a World Cup knockout match since their tournament debut in 1992, with a series of near-misses leaving them with the unwanted tag of "chokers". Sri Lanka have appeared in the last two World Cup finals and won the tournament back in 1996. (Video Courtesy: ICC)
