Bolton has enjoyed an excellent A-League season for Sydney FC and been rewarded with a call up to the national squad for next week's Asian Cup qualifier in Brisbane.

The likes of Adam Federici, Michael Petkovic, Brad Jones and Eugene Galekovic are also in the mix but Bolton hopes to use this week's camp to stake his own claim.

"There's a couple of spots up for grabs for South Africa and if I perform to what I'm capable of, then the possibility's there for me to go to South Africa," said Bolton.

"Apart from Schwarzy, any other keepers can make that squad and I'm excited by that prospect.  I've had a good year. On the back of that I know I can push for a position."

Bolton has been out of the international frame for some time and hadn't previously caught the eye of Verbeek.
