In the latest Spain news, interim boss Fernando Hierro is confident his side can beat hosts Russia in the round of 16.
Spain meet Russia in the first knockout stage after winning Group B, despite unconvincing performances on the way.
It was a shambolic build up to the World Cup for Spain, who sacked head coach Julen Lopetegui on the eve of the tournament, following his agreement to take over Real Madrid without informing the Spanish FA.
They saw that as a breach of contract so dismissed the 51-year-old and put former Real Madrid and Bolton defender Hierro in charge for the tournament.
Despite only scraping past Iran 1-0 and labouring to a 2-2 draw with already-eliminated Morocco, Spain are still regarded as the hot favourites for the tie with the hosts Russia.
Bet365 have Spain at 11/20 to win the game outright, with Russia at 6/1, and a draw after 90 minutes priced at 16/5.
And Hierro, while conceding that Spain have not been at 100% yet in this tournament, insists they can turn on the style when they meet Russia at the Luzhniki Stadium in Moscow on Sunday afternoon.
“We have players that any one of them at any moment can make a difference,” he said.
“We have a lot of faith, that’s most important. The players have worked very well. My players are very fit not only physically but mentally. We want to be positive and believe everything is going to work out well.
“We shouldn’t fear the unknown. Nobody knows the unknown. We have trust in our group and in our players.
“All will be settled on details… we’re starting a new tournament. We have to be positive, have faith in ourselves and believe things are going to turn out well. And we all are positive that it will.”
