Rassie Erasmus has explained what he told Manie Libbok after backing him to start at 10 for the final Rugby Championship Test.

Springbok assistant coach Mzwandile Stick and captain Siya Kolisi are excited to see what flyhalf Manie Libbok will produce on Saturday (5pm) as the Boks look to clinch the Rugby Championship with a win over Argentina in Mbombela.

Springboks hooker Bongi Mbonambi has backed Manie Libbok to rebound from his missed kick in the 29-28 defeat to Argentina in the Rugby Championship. With the game on the line, Libbok had the opportunity to seal the win for the Springboks when he lined up a shot at goal in the 79th minute.

Current and former Springboks have rallied behind flyhalf Manie Libbok ahead of Saturday's Rugby Championship decider against Argentina.

While Springboks coach Rassie Erasmus backs Manie Libbok to come good, they have come up with a plan if his inconsistency off the kicking persists.
