Mexico missed numerous chances against hosts South Africa in their opening FIFA World Cup™ match, having to come from behind to earn a 1-1 draw.
And with that in mind Aguirre has drilled into his players that they must take every opportunity which comes their way. "I have spoken to all of them over the last few days, I have repeated and talked to them (about scoring)," he said.
"Look at Switzerland. They had two chances, scored one and won the game. We had eight opportunities in the first half of our first match and did not convert.
"We insisted to the players that they concentrate on the game all the time, from first to 90th minute. By insisting and stressing you have to score it is a consistent drip and it is psychologically influencing them to do that. So I keep reminding them how important it is to score.
"We will play tomorrow like it is our last match. I don't know how many goals we can score but we will certainly look at testing France's goalkeeper."
Mexico have earned themselves a reputation for an open, fluent style and Aguirre said he had no intention of trying to rein that in just because they are playing the 1998 winners and 2006 runners-up.
"After a year's work we have our own style and we have got players that do that well," he added. "That is our approach and I don't think we should change our style just because we play against a certain team.
"We have come with a certain idea and wanting to win three matches; we didn't succeed in our first so we will try in our second. Whatever happens we are firmly convinced we are going to win the next two matches - we know we have to win those.
"We are not going to disappoint the Mexican people. We have a huge responsibility to make our country proud."
