According to Andres Iniesta, Spain are prepared to forget their experience at Brazil and focus on the Euros.
La Roja were eliminated in the group stages of the 2014 world cup in Brazil, losing to Chile and Netherlands.
But after claiming nine out of ten wins enroute qualification for the continental event, Iniesta believes they are ready to win it for the third time.
Czech Republic provide their opening challenge in France on Monday, and Iniesta is confident Spain are ready to re-assert their dominance.
“The disappointment of what happened in Brazil forces us to be more focused than ever in this competition,” said the Barcelona captain.
“We arrive with a responsibility as champions and we want to go as far as possible. Each tournament is different and I think that we have a good squad and can do well.”
Three points in their Group D opener would be an ideal start, although Iniesta will not be pressing the panic button if Spain fail to win in Toulouse.
He added: “We have started important competitions losing and still won the title, and we’ve started others with victories but ended losing.
“Only at the end of the tournament will we be able to say how important the first match was.”
