The left-back was part of the Selecao side that outplayed the world and European champions to win the Confederations Cup final on home soil in 2013.
And Marcelo has now revealed that following the victory, Spain players paid tribute to the Brazil side for their impressive performance.
“The Spaniards have always respected the Brazil team. I remember after the Confederations Cup, a conversation with Iker Casillas, he told me that was why Brazil always had to be respected,” Marcelo was quoted as saying in O Globo.
“I represent a country, a people. The pressure is much bigger, but the rewards are too.
“It’s a big responsibility. The crowd have warmed to our team and the support helps in difficult times.
“At the Confederations Cup, when the fans sang the anthem a capella, it was like a goal for our team. We entered the pitch 1-0 up. It was awesome.”
Marcelo also praised Brazil coach Luiz Filipe Scolari for his ability to inspire the players and galvanise a team who are under huge pressure to secure their sixth World Cup title this summer.
"He’s an honest, caring person who knows how to get the most out of the athlete. Besides, he’s a winning coach. Not only him, [Carlos Alberto] Parreira also.
“Together, they form a stunning couple. A player likes to work with professionals who are winners, who have been champions, who have stories to tell.”
Hosts Brazil will kick off their World Cup campaign when they take on Group A opponents Croatia in Sao Paulo on 12 June.
