After training at Singapore's National Stadium for the first time on Monday afternoon, Brazil national football coach Dunga did not mince his words when asked about the state of the sandy pitch.

"The Brazil team will always try to produce a good spectacle," he said. "But to do that, you need good conditions. The field here is not very good. Most of it is sand and not grass. It is hard to pass the ball. There is more chance of getting injured on this field. As there is a lot of sand, it can create holes in the ground. But I can't tell now if players will get injured."

Five-time world champions Brazil will meet Asian Cup winners Japan at the National Stadium on Tuesday night, but Dunga's big concern is fatigue among his players, and he is considering sending out his reserves. The Selecao arrived on Sunday morning after beating Argentina 2-0 in Beijing the previous night.

"I will talk to my players to check their level of tiredness," he said. "If they are okay, I will keep the same line-up that played Argentina. It was a long journey to China and the air pollution made the players very tired."
