Italy will take on the world and European champions in Bari on Wednesday and Bonucci can't wait.
"We're playing against one of the strongest sides in circulation," the Juventus centre-back stated on Monday afternoon.
"It's a stimulating challenge," he continued. "But we don't fear Spain, instead we simply respect them.
"The game could be dangerous on a physical level, but we're mentally ready for it. We'll give our all and we are very motivated.
"Spain have some unique players and I'd love to take on Fernando Torres. He has all the characteristics of a modern attacker."
