Spain coach Luis Enrique declared his players unstoppable after their 6-0 rout of World Cup finalists Croatia.
La Roja never looked back after Saul Niguez's headed opener.
Marco Asensio fired in from 20 yards and then, shortly after, saw another rifled effort hit the bar and find the net via Croatia keeper Lovre Kalinic.
Rodrigo, Sergio Ramos and Isco made it a rout for the superb Spanish.
Afterwards, Enrique stated: "It is difficult to overcome a team that presses like Croatia, in fact they had two chances at the beginning of the game in which they could score, but afterwards we were superior.
"The comparisons with the World Cup do not make sense, today we were very effective and everything went wonderfully well, they have had some chances, they have not done it effectively and we have played marvelously with very beautiful goals."
