The incessant buzzing noise of the vuvuzela plastic horn and concerns about the adidas Jabulani ball have hit the headlines since the start of the tournament, but Parreira insists he has no problems with either.

"We love both. We love the vuvuzelas, it's part of our culture and we are used to them, we should keep going with them," said the former Brazil coach.

"We have no complaints with the ball, we've been training with it since March, so the players are more than accustomed to it and we have no problems.

"I understand that some people and some players have a problem with it but we've had no problems with the vuvuzelas or the balls."

Parreira also believes it is premature to talk about the standard of the matches and lack of goals at the World Cup so far.

Speaking ahead of his side's second Group A match against Uruguay tomorrow, Parreira said: "I believe it's too early to make a judgement.

"Teams are going to grow during the tournament, there is a lot of tension, for both the big teams and the small.

"The World Cup really starts in the round of 16.

"I think it's too early, one round is not enough to make a judgement about the World Cup. As the tournament progresses I believe the standard will be much better."
