RIO DE JANEIRO — The Confederations Cup begins following protests that turned violent in three of Brazil's biggest cities, while builders were still slapping cement on stadiums.
The eight-nation tournament, a test of Brazil's organizational ability a year before the World Cup, starts Saturday in the capital Brasilia when the Selecao hosts Asian champion Japan. It ends June 30 in Rio de Janeiro's Maracana Stadium.
The quadrennial tournament is held every four years — always one year before the World Cup — among the champions of each soccer confederation, the World Cup champion and the host.
Workmen still were applying cement onto walks, attaching glass panels and painting at several stadiums as kickoff approached, but FIFA President Sepp Blatter said he was not worried about the late preparations.
"There's a lot of work that will be done in the last minute," he said. "So for me it is not a surprise that two days to go there is still work somewhere. It means that something is not finished so we should just say, OK, and finish it."
While the paint and cement dry, tournament officials have been monitoring street protests, handling team complaints and hoping Nigeria arrives on time.
In the capital Brasilia, about 200 people burned tires and blocked the main road in front of the stadium that is the site of the opener. The protest was organized by local groups complaining about the excessive cost of the Confederations Cup and World Cup. A black cloud of smoke was seen near the stadium Friday morning as protesters held banners complaining about the local government.
Thousands of protesters marched in Rio and Sao Paulo on Thursday to rage against increases in bus and subway fares, and some clashed with police.
