#4 Sergio Ramos
It would have been easy to place a lot of the players on the Spanish squad on this list. We have already had Gerard Pique make an appearance, and the tournament is also going to be the last time we see either David Silva or Iniesta represent their country on the grandest stage in football.
The loss of Sergio Ramos, the team's captain and all-time outfield appearance record holder will be a major blow for them though, especially as the pairing of Ramos and Pique is almost definitely going to be gone come 2022.
The Real Madrid star has had a solid season for Los Blancos, one topped off with a controversial performance in the Champions League final against Liverpool, and he will be hoping to bow out of the World Cup lifting a trophy above his head as well.
