During a frustrating evening at the Kazan Arena when the 2010 champions struggled to break through the stubborn Iranian defense, Diego Costa scored on a deflection for a 1-0 win on Wednesday.
Finally, in the 54th minute, Spain scored the goal which reflected their superiority, though the goal itself was fortuitous at best.
"We only care about sporting matters", he said.
It proved the only goal of an entertaining match, although Iran saw one attempt chalked off for offside with help of the VAR.
The Iranian national team's official Twitter accounted posted a photo of a female football fan in the stands of the Azadi Stadium in Tehran, holding a flag as she watched her team play Spain via a broadcast.
"The team sits back and that is a tactical strategy that is part of the game", Carvajal said.
"If there was a magic potion to stop the Spanish team, then $1 million would not be too much to buy it, even though we do have some financial troubles", said Queiroz, who was flanked by AEK Athens midfielder Masoud Shojaei.
Iran is going into the game against Spain with a win against Morocco.

A further 10 countries agreed to participate in Opec's supply cuts, with Russia, Kazakhstan and Mexico as the leading producers. Zanganeh has said that if OPEC returned to regular compliance, the group would raise output by around 460,000 bpd.
"For each player playing in the World Cup is an honor and I am here so I'm happy".
Spain and Portugal are tied at the top of Group B with four points each, one more than Iran. The Atletico Madrid striker showed his individual class and poaching instincts with both goals and will be charged with breaking the deadlock against a mean Iranian defence.
But Hierro insists the problems posed by Iran - who thought they had equalised only for Saeid Ezatolahi's effort to be ruled out by the video assistant referee - indicate there can be no guarantees in Russian Federation.
Spain will face Morocco and Iran will take on Portugal to wrap up Group B play on Monday.
"We are only on the bench and we try to do as little as possible during the game".
Champions in 2010 and among the favourites this year, Spain's World Cup ambitions were kept in check, nearly single-handedly, by a stunning Cristiano Ronaldo hat-trick. "We just hope things happen the way we want".
After Wednesday, Team Melli will finish their group stage campaign on June 25 against Portugal, which will pose a different but equally hard obstacle.
