Sibaya has asserted that neither Iraq nor New Zealand should be treated as simple fixtures in the Confederations Cup.
The experienced midfielder is sure to be a fundamental part of coach Joel Santana's plans for the Confederations Cup.
Sibaya explained, "I have been involved in the World Cup finals in 2002, the African Nations Cup in Mali the same year, and again in Tunisia in 2004 - no game in a major event is easy.
"Neither Iraq nor New Zealand will be pushovers. They are not champions of their regions for nothing."
Bafana end their Group A programme against European champions Spain in Bloemfontein on June 20.
Sibaya commented, "We all know plenty about Spain, but we must be wary as little is known about either Iraq or New Zealand and that makes them dangerous."
Sibaya said he was looking forward to getting a run against Poland. "Poland is a test in that it will help us work out our final tactics and give us a chance to play a decent side under competitive match conditions," he commented.
"To me, this is a good game to play a week ahead of our vital clash against Iraq. It is not so much the result that matters against Poland, but that we follow instructions and keep building up our confidence."
