Bosnia coach says players will give their all in World Cup opener against Canada
Bosnia will aim to progress beyond the group stage this time after securing just one win during their debut in Brazil in 2014.
"We are a small nation," said Barbarez. "This is only our second World Cup and we are certainly seen as underdogs in many of the matches ahead."
Despite being ranked 64th, the coach is optimistic about his team's ability to shine on the global stage.
"If you look at our results, I think you have to simply admire what we have achieved."
Bosnia secured one of the six remaining World Cup spots by beating three-time champions Italy in a penalty shootout. They are a side that breaks hearts and plays with passion, and they intend to carry that same spirit into the tournament.
"(I once said) I love this story of David versus Goliath," Barbarez said. "We play with our hearts and that has been our strength."
The Dragons are captained by 40-year-old striker Edin Dzeko, who Barbarez confirmed will be in the squad for Friday's match after recovering from a shoulder injury. Dzeko is Bosnia's all-time top scorer with 73 goals.
"Edin will be with us tomorrow," Barbarez said. "Edin will play just as usual."
Canada match will be 'quite intense'
Barbarez expects a tough encounter against Canada, who are also aiming to reach the knockout stage for the first time but face the added pressure of chasing their first ever World Cup victory and playing on home soil.
"I might be exaggerating a little but I am sure (the game) will be quite intense, which is typical of both teams," Barbarez said.
While Canada will have the home crowd behind them, Bosnia will also enjoy strong support. The Dragons have received a warm welcome since arriving in Toronto, with fans flocking to the team's training sessions this week.
"We really want to show our best to the whole world," Barbarez said. "We really want to be the team that earns respect and we can only do that by showing what we know on the pitch."
