Carlos Queiroz has had his contract with Iran extended through to the 2014 World Cup after successfully guiding the nation to next summer's finals.
The West Asians secured a fourth appearance at the tournament following their 1-0 defeat of South Korea on Tuesday.
And the result means Queiroz, who was appointed Iran boss in 2011, has triggered an extension in his contract, allowing him to lead his side in Brazil.
"My contract is such that it goes step-by-step in accordance with the interests of the [Iranian] Football Federation," Queiroz was quoted as saying by the Fars news agency.
"After qualification to the World Cup it has now been extended until the end of this competition."
"The Korean coach created an unusual atmosphere before the match. In my 32 years of coaching, I've never encountered such an issue," Queiroz said.
"Talk of war, revenge and blood is not normal. The Korean coach wanted to put our players under pressure with such talk but we used it to motivate our players."
