'Los Cules' may have won La Liga and the Copa del Rey but it is Real Madrid who boast the most players in Julen Lopetegui's list for this summer's tournament.
Barring any injuries in the Champions League final, Real have six Spanish players heading to Russia: Sergio Ramos, Dani Carvajal, Nacho, Isco, Lucas Vazquez and Marco Asensio.
It is the first time since 1962 that so many Madrid footballers will be playing in a World Cup for Spain.
In recent times, it has been Barcelona who have been dominating the Spanish national team, helping the country to European Championship success in 2008 and 2012, in between world success in 2010.
However, for Russia, 'Los Cules' will have just four: Gerard Pique, Jordi Alba, Sergio Busquets and departing Andres Iniesta, who will retire after the competition.
The next biggest contingent is Atletico Madrid with three.
