Chile coach Marcelo Bielsa has called on his side to be positive in their last-16 meeting with Brazil.
La Roja have an abysmal record against Brazil having suffered a total of seven defeats over the last decade, but the coach is hoping to turn that into a positive.
Bielsa is hoping his players can overturn their poor record against Brazil and dump out their South American rivals.
"I think the psychological aspect is always very important in a competition," said Bielsa.
"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."
Chile finished second in Group H to Spain and Bielsa hopes they can learn from the defeat last time out to European champions Spain.
"The teams gradually change according to the games they play," added Bielsa.
"We have played three matches in this World Cup and I think these matches have strengthened our experience.
"Especially the last match against Spain, which I think has similarities to tomorrow's match.
"We hope that the experience will help enhance our chances so that we can try to keep progressing in this tournament."
AbsenteesChile will be missing two of their key players - Gary Medel and Waldo Ponce - who are suspended, but Bielsa is confident they have enough strength in depth to cope with Brazil.
"As for the absences of Medel and Ponce, they've had a very good performance so far," noted Bielsa
"They are no doubt valuable, but I think we are in a position to put other team-mates on the pitch that can do the same job."
