Vicente del Bosque's men received their fair share of criticism after Euro 2012 for their methodical style of play, but Xavi feels their comprehensive 4-0 victory over Italy in the final proved La Roja can be as entertaining as they are effective.
Consequently, the midfielder does not pay any heed to those who have an issue with Spain's considered approach to the game.
"It's true that we were criticised for being boring at Euro 2012, yet that 'boring' team beat Italy 4-0 in the final," Xavi told the Times of India.
"Italians are always better defensively. Yet we could beat them with a handsome margin. So, we are not at all worried with what people opine."
Spain were hammered 3-0 by Brazil in the final of last year's Confederations Cup, but Xavi feels last year's experience will help them this summer.
"We were beaten by a rejuvenated Brazil, playing in their backyard," the Barcelona playmaker admitted. "We were tired but I do not like to find excuses. We were beaten fair and square.
"We tried to analyse our performances after that and believe we played quite well in the remaining qualifiers of the World Cup.
"What I feel is, playing in Brazil exactly one year earlier will be of immense help for all of us. We are familiar to the conditions.
"We played five matches under variable climatic conditions. We'll have to play under almost similar conditions this time. It should help us play better."
