Barcelona star Lionel Messi admits there's growing confidence within the Argentina squad of World Cup glory.
Messi is joint top scorer at the tournament so far.
"I'm happy that we've advanced as first of the group, that's what we wanted. From now on, you don't want to do anything wrong, because one match can send you out. We want to continue on this path and improve. We've seen a better Argentina and we hope to raise the bar.
"I don't think there is anything more wonderful than being the World Champion. I want to achieve that with my national team to give joy to my country. It would be incredible."
