The Italian's contract with the national team runs out after the 2014 World Cup, with speculation that he could then step down.
However, the 56-year-old insisted that he is concentrating on the upcoming qualifiers and nothing else.
"I'm not bothered about the speculation," Prandelli told reporters.
"I am solely concentrating on our World Cup qualifiers.
"I know that I have a job that attracts a lot of rumours but I have not yet decided what I will do."
