MARCELO Bielsa wants his Chile players not to carry a "gloomy" feeling onto the field when they come up against Brazil in their last-16 World Cup encounter tomorrow.
La Roja have an abysmal record against their South American rivals having suffered a total of seven defeats over the last decade, but the coach is hoping to turn that into a positive.
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."
The Argentinean has seen his team enjoy a good competition so far with wins over Honduras and Switzerland helping them finish second in Group H behind winners Spain, who they lost to in their final group match.
And Bielsa hopes they can learn from that loss to the European champions.
He continued: "The teams gradually change according to the games they play.
"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."
Chile will be without two of their key players - Gary Medel and Waldo Ponce - who are suspended, but their boss is confident they have sufficient strength on the bench to cope with Brazil.
He added: "As for the absences of Medel and Ponce, they've had a very good performance so far.
"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."
