Chelsea star Juan Mata feels Spain are going through their best period ever and is proud that opponents are extremely motivated to knock la Roja off their perch.
Vicente del Bosque's men are the reigning European and world champions and Mata is pleased with the way they have dominated football in recent years.
"Spain are enjoying the greatest period in their footballing history and, of course, our opponents want to knock us off our perch," Mata told Fifa.com.
"But it makes us feel proud when we experience this, that playing against us is seen as special.
"One of the lads said that a club-mate of his, ahead of a friendly match against their national team, asked him to tell us not to go all-out against them, because we were playing really well."
The gifted attacker then looked ahead to this summer's Confederations Cup and stressed that Spain are determined to emerge victorious in Brazil.
"We’ll get to see what the stadiums are like, have a taste of the atmosphere – which I’m sure will be great, and also start preparing for next year’s World Cup.
"When you’re going to play in Brazil, the Maracana always comes to mind. It’d be fantastic if we could reach the final there and win it."
Spain meet Uruguay, Nigeria and Tahiti in the group stages of this summer's competition.
