The Inter midfielder believes that Luiz Felipe Scolari's Selecao can handle the weight of expectation this summer and win the tournament for a sixth time on home soil
The Inter midfielder has 23 Selecao caps to his name and has been a mainstay of Luiz Felipe Scolari's second spell as national team coach, having been part of the squad who won the Confederations Cup in 2013.
Hernanes acknowledges that the Brazilian public have high ambitions for their side this summer but feels that the players are capable of matching them.
"This pressure is always on us because we are playing at the highest level," the 28-year-old told The Times of India.
"We are used to feeling it. Having said that, I want to do well in front of people of my country.
"The joy was crazy [when I was named in the squad] because it was my life dream to be part of the group. I am very happy and proud to have reached this point in my career. Brazil are already on top and now we get the chance to play in our country. This situation will bring the best out of us.
"I do hope Brazil [will win]. Look out for Argentina and Germany. It's the great schools that make a difference in a World Cup."
Hernanes has enjoyed four fruitful seasons in Serie A since moving from Sao Paulo in 2010, making 156 appearances and scoring 42 times for Lazio before moving to Inter in January for €15 million (£12.1m), and he hopes that the Nerazzurri can be a path to greater success.
"When I came to Inter, I told myself, 'I won't think of doing great things but only work hard and things will arrive on their own'," he continued. "Important things have already happened: the first goal at San Siro [in a 4-1 win against his old club, Lazio, in May] and, now, making the World Cup squad.
"With Brazil, I want to bring the same winning spirit that I have with my team-mates in Inter."
Hernanes also spoke of his adulation for Inter great Javier Zanetti, who retired at the end of the season after making more than 800 appearances for the Italian giants.
"Being 40 years old, he still continues to train like he is at his peak and you always find him ready," the Brazilian added.
"All this makes me think of how many sacrifices he has made to keep this mental and physical state. During his farewell, I saw the affection and respect that the fans and club had for their captain and this motivated me further."
