Brazil coach Dunga insists that past records will count for nothing when they come up against Chile in the last 16 of the World Cup at Ellis Park.

The five-time champions have won the past seven meetings between the two sides dating back almost 10 years and take a major psychological advantage into the game.

However, the Selecao boss, whose side finished top of Group G with two wins and a draw, thinks otherwise.

"This is merely a statistic, nothing else," he said. "What is important is our performance on the pitch against Chile.

"My players always know that it's the next game that is the most important one. For now our next game is going to be against Chile, so we will prepare as we do against any other team.

"The past is in the past."

Marcelo Bielsa wants his Chile players not to carry a "gloomy" feeling onto the field as a result of their torrid record against Brazil.

He said: "I think the psychological aspect is always very important in a competition. It's more of a factor of motivation for us in my point of view. We have the chance to reverse a historical negative trend for Chile.

"We shouldn't think that because we were beaten by them in the past we must go on the pitch gloomy. No, we should acknowledge our past record, but must also aspire to try and find a place for ourselves.

"One is always enthusiastic to change history when history is not favourable.

"Each match gives us the opportunity to do that and tomorrow's match is a very attractive opportunity for us to reverse that trend."
