Durban - Jean de Villiers knows that he has to prove his worth to coach Heyneke Meyer when he leads the Springboks against Argentina at Kings Park on Saturday.
De Villiers will play at outside centre and start his first Test since November 2014 when a knee injury threatened to end his career.
But eight months of intense rehabilitation later, De Villiers is back in the Springbok starting line-up, though he is under no illusions that his place in this year's Rugby World Cup squad is guaranteed.
"I have to do well and perform to make the 31-man squad. I'm not injured anymore, the emotion is gone," De Villiers said in Durban on Friday.
"Each guy here is good enough to represent their country and you have to perform to show the coach that you are good enough to play, and it is no different for me. My job is to perform."
In his absence, De Villiers said he had been extremely impressed by the centre combination of Damian de Allende and Jesse Kriel.
"They've been unbelievable, individually and as a combination. Sometimes you put two great players together and they don't combine well... but as a combination these guys have done really well," the Bok captain said.
"The fact that the other guys played well I don't think puts more pressure on me. I need to prove to myself and the guys who select the team that I'm good enough, and that's the most important thing.
"Competition within a team is a good thing if approached the right way."
Saturday's clash kicks off at 17:05.
