Uganda goalkeeper Denis Onyango and Namibia forward Peter Shalulile played key roles as Mamelodi Sundowns beat Kaizer Chiefs 2-0 on Sunday to top the South African Premiership.

Veteran Onyango, widely regarded as one of the best shot-stoppers in Africa, made several superb saves when the hosts were clinging to a one-goal lead during the third-round match in Pretoria.
