KAZAN, Spain defender Dani Carvajal has been recalled for Wednesday's World Cup match against Iran, replacing Nacho from the starting side that drew with Portugal, after recovering from a hamstring injury.
Iran started the second round of fixtures top of Group B having beaten Morocco in their opening game, while Spain needed a win after a thrilling 3-3 tie with Portugal.
If Spain is able to put the ball into the back of the net the way they did against Portugal, then Iran better up their offensive play.
Iran thought they had equalised soon after though, with Saeid Ezatolahi blasting home from close range, only for VAR to correctly chalk it off for offside.
Queiroz said he was proud of the performance of his players and insisted they will continue to confound expectations as they head into their final group game against Portugal.
But the Persians kept their shape superbly, restricting Spain to a handful of chances from David Silva in the first half.
SHOWED POWERS OF ENDURANCE: Iniesta, as expected, departed with 20 minutes left and Vazquez - who struggled to make much of an impact - soon followed.

Spain's frustration was in danger of boiling over shortly before the interval when Costa got involved in an unnecessary spat with Beiranvand, although referee Cunha opted not to punish the combative striker.
Costa, who also scored two goals in the opening match, has three goals at this year's World Cup, trailing Ronaldo by one.
And while goalkeeper Alireza Beiranvand recognises few will fancy Iran to add to their current points tally, he is in a defiant mood and insists Spain will be in for a battle. Whose side are you as the Spaniards take on the Iranians?

Iran kept a firm head on all fronts, despite David Silva's attempted volley that sailed over the crossbar after 30 minutes.
It promises to be an interesting game as Iran and Spain meet for the first ever time.
