Ahead of the Goal 50 announcement next week, we want to know who you think deserves to be named as the greatest defender in the world for their performances in 2013-14
Atletico Madrid's defence was crucial in them winning La Liga and reaching the Champions League final - goalscoring centre-back Diego Godin and flying full-back Filipe Luis particularly pivotal.
Across the city, Sergio Ramos was making a solid case for being the best centre-back in the world as the main man in Real Madrid's back four. Paris Saint-Germain would not have been the same title-winning side without their captain Thiago Silva, who carried Brazil's defence in a similar way before they crumbled in the World Cup's latter stages.
Mats Hummels had no such problems this summer, maintaining his Borussia Dortmund form to help Germany win the World Cup. Pablo Zabaleta, contrastingly, faced up to final failure with Argentina - though he was nothing but a success in England after another title-winning year with Manchester City.
This campaign was a breakthrough year for versatile Netherlands and Ajax defender Daley Blind and Toulouse's Serge Aurier, both of whom have been linked with transfers to top clubs this summer. Similarly, Mehdi Benatia's sterling performances in his debut Roma season have caused a swarm of interest in his signature.
And he might be at the tail end of his career, but Mexico's Rafa Marquez became the first player to captain his nation at four World Cups this summer - an achievement which could be impossible to match.
