Chile's squad, which has the youngest average age of all the South American teams, boasts one of the World Cup's potential stars in 21-year-old forward Alexis Sanchez, midfielder Rodrigo Tello told Reuters.
Sanchez, who plays for Italy's Udinese, has scored three times in his last four Serie A outings.
"We have a lot of players who have a lot of hunger, they want to play like they did in the street before, at home," said Tello, whose name reverberated around Europe in November when his goal secured Turkey's Besiktas a 1-0 win over Manchester United at Old Trafford which ended the Premier League side's 23-match unbeaten home record in the Champions League stretching back to 2005.
"They like putting on Reggaeton music in the team bus," he added with a wry smile, referring to a blend of Reggae, Latin music and Spanish-language rap.
At 30 and a family man, he is one of the veterans in the squad having won a bronze medal with Chile at the Sydney Olympics in 2000.
"We have a very young team and we are working with a new coach who has changed our mentality. We had a very tough qualifying and now all the Chilean people expect a lot from us."
