Chelsea striker Alvaro Morata has missed out on being named in Spain's squad for the 2018 World Cup.
The former Real Madrid forward has struggled for form in the second half of his first campaign at Stamford Bridge, scoring 15 goals in 47 appearances for the Blues.
Morata has previously scored 13 goals in 23 appearances for La Roja, but the likes of Diego Costa, Iago Aspas and Rodrigo Moreno prefered by Julen Lopetegui.
The 2010 winners have followed England's lead in naming their 23-man squad well ahead of time rather than an extended provisional roster as they look to win their fourth major tournament in a decade.
David de Gea is set to start in goal after another fine season for Manchester United, with Clasico rivals Sergio Ramos and Gerard Pique the established centre-back pairing.
Arsenal's Nacho Monreal is preferred to Chelsea's Marcos Alonso to provide competition for Jordi Alba at left-back while Madrid duo Dani Carvajal and Nacho will fight it out for a place on the opposite flank.
Sergio Busquets, Andres Iniesta and David Silva are likely to be Lopetegui's first-choice midfield trio, with Isco depolyed slightly further forward.
Atletico Madrid are represented by creative duo Koke and Saul Niguez while Bayern Munich's Thiago Alcantara and Madrid duo Marco Asensio and Lucas Vazquez provide options off the bench.
