Kaizer Chiefs and Orlando Pirates might have been knocked out of the Nedbank Cup, but that does not make life any easier for Mamelodi Sundowns, says defender Ramahlwe Mphahlele. Sundowns survived a giant-killing weekend, beating hoodoo side Platinum Stars 3-1 in the last 16 at Royal Bafokeng Stadium in Phokeng, North West, on Sunday.They have been drawn against Mpumalanga Black Aces in the quarterfinals, a repeat of the 2008 final won by the Chloorkop side thanks to a late Lerato Chabangu volley.Unlike in the league, in which Sundowns have to rely on PSL rivals to derail leaders Kaizer Chiefs, Sundowns have their Cup destiny in their own hands.But Mphahlele said Supersport United and Bidvest Wits could not be ruled out of lifting the trophy."You still have Wits and Supersport. You cannot rule anybody out," Mphahlele said."We can't just say because Chiefs and Pirates are out we are the favourites. This cup is known for disappointments, so we have to be very careful. We have to work [hard to win] the trophy."The league is not in our hands, but the Nedbank Cup is. If we win all the games in this competition we win it. We are happy with the draw because we are playing a PSL team, which means we know who we are coming up against."United, who beat defending champions Orlando Pirates 1-0 in Polokwane on Saturday, will face National First Division leaders Golden Arrows and will be wary of the threat posed by their former player, Mabhuti Khenyeza.First division side Black Leopards, who stunned Chiefs on Saturday with a 2-1 victory, will host first division rivals Vasco da Gama, while Wits are away to Ajax Cape Town...
