Fernando Torres believes the current Spain squad is "a lot better" than the one that lifted the 2010 World Cup trophy in South Africa.
Spain's title defence started on the worst possible note after they were dismantled 5-1 by the Netherlands in their Group B opener on Friday - a repeat of the final four years ago, when la Roja won 1-0 after extra-time.
But speaking ahead of Spain's second Group B fixture against Chile on Wednesday, Torres said the team in Brazil was an improvement on the side that took to the field four years ago.
"There is nothing to say that the team is worse, I would say it is a lot better,” Torres told Fifa.com.
"Mentally I think the team is prepared for a situation like this. This group has gone through very good and very bad moments together.
"We know what we are capable of and I don't think the psychological factor will be a problem."
Vicente del Bosque's squad have been criticised for being too old following the defeat in Salvador, which was the first time Spain had conceded five goals in a match since losing 6-2 to Scotland in 1963.
But Torres believes age has improved the side and sees no reason for a change of philosophy.
"The team has matured with age," he said. "There is no reason to change our system. In South Africa we lost the first game and we kept doing the same and were champions.
"We have to think that this team still has a lot of football ahead of it to achieve things once more."
"There will be a lot of people that believe in this team, that we have seen lift us up in similar situations and that will be with us."
Defeat to Chile at the Maracana would spell the end of Spain's quest to retain the world title if Netherlands beat Australia.
