Portugal attacker Simao insists his team do not fear Spain ahead of their second round clash.
The two neighbors square off in Cape Town on Tuesday in a mouth-watering fixture, as both look to progress to the quarter-finals.
European champions Spain have been tipped by many to go all the way in South Africa this summer, although they were beaten 1-0 by Switzerland in their opening game.
Simao, 30, accepts that they will be tough opponents, but insists Portugal will not be afraid.
"They're one of the best teams in the world," he said.
"They have a style of play like Barcelona, with lots of players from Barca, who play with two or three touches of the ball.
"But it's 50-50. Without showing them a lack of respect, we're not scared at all. We've got a great team too.
"And to become better, we have to beat Spain. They're champions of Europe, but we have our own qualities."
The Atletico Madrid man is hoping for an aggressive performance from Carlos Queiroz's men.
He added: "You have to be aggressive. I don't mean committing fouls, but pressure the ball carrier and play our own game.
"They like keeping the ball, but it's not always the team that has the ball that wins. For the tactics, I don't know. It's the technical staff that decide."
