Quinton de Kock expects Faf du Plessis to captain South Africa in the ICC T20 World Cup next year but says he would grab the opportunity "with both hands" if he was asked to take over.
De Kock led the Proteas in a drawn Twenty20 series with India in September as Du Plessis was given a rest.
The wicketkeeper-batsman will also skipper Cape Town Blitz in the Mzansi Super League, but he believes Du Plessis will lead his country in Australia next year.
De Kock told ESPNcricinfo: "The way I see it is that I was just a replacement. That's the way I took it. For now, it's still Faf's baby. But maybe if things change and they do want me to do it, then I will do it.
"For the moment, I am not looking too far ahead. I am just trying to look at how I can help out with the youngsters, with the new guys in the T20 team and by myself, just getting better and getting ready for the T20 World Cup next year.
"But if that does come upon me, then I will try to grab it with both hands."
De Kock says South Africa can take inspiration from the way England turned around their fortunes in limited-overs cricket to win the Cricket World Cup this year.
"We are not the first team that has gone through a transition," De Kock said. "England did it after their last World Cup and look at them. Four years later, they end up winning the thing.
"It's alright if the whole country and guys are a bit down and out but when we all gather together, especially after winning this Rugby World Cup, a lot of people are pumped up.
"[People] want to get this transition going so, by the time we get to our next World Cup, we can really put ourselves in a good stead, just like England did."
