A Brazil lineup bursting with global football stars will open their World Cup campaign against a North Korea squad they, and pretty much everyone else, knows very little about.While five-time champions Brazil have won more titles than any country at football’s biggest showcase, North Korea haven’t played in the tournament in more than 40 years and their international isolation is about its only advantage ahead of Tuesday’s (today’s) match at Ellis Park.The unpredictability surrounding the secluded Asian nation is making Brazil wary of an upset like the one the team from the reclusive communist state pulled in 1966, when they beat Italy en route to the quarter-finals in their only previous World Cup appearance.“I don’t know anything about them,” Brazil’s Ramires said on Sunday. “I only watched half of a warmup match they played. We are still waiting for the Brazilian coaches to give us more information about the them.”That is information which may be hard to find considering that the North Korea squad has been mostly secluded from public view and the media at a remote hotel in the northern outskirts of Johannesburg since arriving in South Africa.But North Korean coach Kim Jong-Hun said on Monday he is plotting one of the biggest shocks in World Cup history when his side take on five-time champions Brazil. “Our Group G opponents are very strong,” the 53-year-old told FIFA’s website.“But in football, the best teams don’t necessarily win. We will give it our best. We know we need to win to reach the knockout phase, so no matter who we’re up against, we’ll target the three points.”“We have to respect the Koreans,” Brazil midfielder Elano said. “When we look at history, Brazil may have many more titles than they do, but once the match starts we will need to have the same respect as we would have to any other team.”Brazil have a revamped squad following its disappointing 1-0 loss to France in the quarter-finals of the 2006 World Cup in Germany. With few squad changes since he took over, Dunga helped Brazil win the Confederations Cup last year and finish first in South American World Cup qualifying. Brazil also beat Italy, England, Portugal and Argentina in friendlies ahead of the World Cup. “The team is ready,” Robinho said. “The team has been ready for a long time. We are prepared to do well in this World Cup.”Robinho, Kaka and Luis Fabiano highlight the team’s attack, but another strong point this time should be the defence featuring goalkeeper Julio Cesar, Lucio, Juan and Maicon.“We expect to play against defensive opponents, which always causes difficulty, and because its the first game, the anxiety is very great,” said midfielder Gilberto Silva.
