Spain defender Sergio Ramos believes the 1-1 friendly draw with Germany on Friday demonstrated the team's considerable potential ahead of the World Cup.
La Roja arrived at the previous edition of the tournament in Brazil four years ago as holders, but crashed out in the group stage after losing 5-1 to Netherlands.
Head coach Vicente del Bosque could only guide them to the round of 16 at Euro 2016 and stepped down after the tournament, making way for Julen Lopetegui.
A convincing qualifying campaign has Spain back among the favourites ahead of this year's finals.
And Real Madrid defender Ramos, who earned his 150th senior international cap in Dusseldorf, feels his side made something of a statement with their performance against Joachim Low's men.
