Neymar scored one superb goal and made another in a 2-0 victory that sent the hosts into the semi-finals, while Mexico's elimination was confirmed by Italy's 4-3 win over Japan in the second Group B game.
"We conceded a goal at the start, with a great effort from Neymar, which changed the circumstances," said De la Torre.
"We had a certain amount of dominance for a large portion of the game, but we lacked enough precision to score. And at the end, there was a great contribution from Neymar (setting up a goal for Jo), which made it 2-0."
Mexico have now won just once in 11 games in 2013, which has left their hopes of qualifying for next year's 2014 FIFA World Cup Brazil™ in the balance. However, De la Torre said he was not disheartened by their current situation.
"We've not achieved our objective," he said. "But it's not a setback.
"We're on track. The principal objective is qualification for the World Cup. In this competition, we didn't manage it. That's how it is."
Mexico will play Japan, who have also been eliminated, in their final FIFA Confederations Cup group game in Belo Horizonte on Saturday.
