Carlos Queiroz has stated his intention to leave his position as Iran coach after the FIFA World Cup.
The Portuguese extended his contract with the Asian nation in June, with that deal lasting until the end of the tournament.
The Iranians began their World Cup campaign with a 0-0 draw against the Super Eagles of Nigeria on Monday.
Queiroz revealed that the Iranian Football Association had offered him the chance to stay, but the former Portugal coach believes financial restrictions mean that he cannot take Iran any further.
“I will end my relationship (with Iran) after the World Cup,” he told Portuguese publication Publico.
“There was a moment when Iran proposed me to stay, and they still do show they want me here.
“But there is not enough support from the government, and it’s clear this interest, in fact, is over, due to financial conditions, to keep doing the job we have been developing at the national squads.
“The dialogue is over, and I already decided that I am not going to stay.”
After the drawn game against Nigeria in their Group F opener, the Iranians now must prepare for a showdown with Argentina, who are considered one of the favourites to win the tournament.
The 61-year-old admits Iran Will face a near impossible task against a team he considers among the best in the world, but believes his side will be fully prepared.
“Argentina carry a top world football reputation,” he commented. “It’s difficult to find another national team with so much credibility and reputation. They are among the top five teams in the world.
“You could only be ready for Argentina if you had 20 years of football preparation. Now the objective is to have our players mentally and physically fresh to play this game,” the former Real Madrid boss concluded.
While Iran will be battling Argentina, the Nigerian side will be seeking a win over Bosnia on Saturday.
