#4 Sergio Ramos
Sergio Ramos is the Spanish squad's most experienced player, having played in 13 World Cup matches so far in his career. Further, he is the captain of the side and will try to lead from the front.
The 32-year-old has just won his 3rd consecutive UEFA Champions League title with Real Madrid and will be extremely high on confidence. A bulwark at the back, Ramos will play alongside Gerard Pique at the centre of Spain's defence, forming one of the most intimidating defensive partnerships.
Ramos is widely recognised as one of the best defenders in the world and has made a staggering total of 151 appearances for the national side. If Spain are to stand a chance at winning the World Cup, a lot will depend on Sergio Ramos' solidity at the back.
