SAN CRISTOBAL, Venezuela, Oct 12 (Reuters) - Brazil coach Dunga complained of a hostile reception in Venezuela, saying his players were kept awake at night and that some suffered stomach problems.
"When we play away from home in the World Cup qualifiers, the whole country unites to try and make things as difficult as possible for Brazil," he told Brazilian reporters after the 4-0 win.
"They left us stuck in the plane for an hour and a half. Inside the hotel, we also had numerous difficulties during the night.
"There was a discotheque and a lot of shouting near the players' rooms. Four or five players were ill because of the food. This creates a certain difficulty."
Dunga also complained that a Brazilian flag was burned at the Pueblo Nuevo stadium and the national anthem was jeered.
"We show respect for all the teams and ask for respect for us," he added.
Brazil raced to a 3-0 lead in only 19 minutes with Kaka scoring the first goal only six minutes into his first international for 11 months.
"It's very good to be back and even better to score a goal on my return," said Kaka.
"If we continue playing like this, we will be difficult to beat."
Media reports said the delay in getting off the plane was caused because the stairway originally brought to the door was too low and another had to be found.
Venezuela coach Cesar Farias, whose team have taken one point from five matches under his leadership, said his side had paid for missing chances.
"We can't understand that people don't like it when we say that Brazil were better than us, it's something we have to accept," he said.
"I was unhappy at the number of chances we missed in the game, including one at the start which could have changed the whole story," he said.
