On a day when a transport workers's strike brought part of Brazil's biggest city to a halt, Brazil's Sports Minister says it's impossible to promise his country will be ready for this week's opening match of the football World Cup.
Aldo Rebelo says they have done everything within their capacity so that things are as close as possible to ready.
Large parts of Sao Paulo came to a standstill after a strike by metro workers prompted people to take their cars to work.
It was the latest in a series of stoppages to hit Brazil in recent weeks.
Police, teachers and bus drivers have also been on strike in search of higher wages, causing fears that the tournament, which kicks off next Friday when the host nation faces Croatia, could be affected.
However, the 12 stadiums should be ready, even though workers are still putting the finishing touches to some of them.
