Spanish midfielder Xavi is not under-estimating the challenge ahead at this summer's World Cup.
Spain are 7/2 favourites with Sky Bet to lift a first-ever world crown to add to their European championship success two years ago.
Before that victory, Spain were seen as perennial underachievers but Xavi believes the side can again produce the goods in South Africa, although he acknowledges it 'will not be easy'.
He said: "We have changed very little (from the European championship success), a few players, the coach, but... we practically have the same squad and there's a good atmosphere in the squad.
"It's in our hands. (But) it will not be easy, that's for sure.
"We will have to be cautious and progress carefully, although with the belief that we are confident facing any team.
"We will see whether it's true that the time has come for Spain to win the World Cup."
Spain face Switzerland, Honduras and Chile in Group H but Xavi is taking nothing for granted.
"On paper, Chile is the strongest rival," he added.
"But we are talking on paper: on the pitch, a lot can happen."
Meanwhile, Villarreal defender Joan Capdevila believes their first Euro title success since 1964 can help their bid.
"We have won the respect of our opponents, which we did not really have before," said Capdevila.
"Our fighting spirit has improved, as well as our skills, and I believe our opponents fear us much more than they did before.
"We've made a lot of improvements in the last two years and it's clear that on the whole we've progressed."
