Spain coach Luis de la Fuente opted not to include defender Dean Huijsen, who, sports newspaper Marca writes, was the only realistic option. Dani Carvajal has had major injury problems and was also left out.
This is the first time in Spain's 16 World Cup finals that no Real Madrid player is in the squad.
Injured Barcelona star Lamine Yamal has been dropped from the squad. The 18-year-old is expected to miss Spain's World Cup opener against Cape Verde on June 15 and possibly the second match against Saudi Arabia.
But there is hope he will be fully recovered for the final group game against Uruguay.
