Since then, fans have witnessed a Ronaldo-Messi duopoly, with the two taking home 11 of the 13 awards since. In 2019, we saw a defender finish in the top three for the first time in over 10 years, as Virgil van Dijk finished second behind Lionel Messi.With defenders finally in the running for the top awards, let's take a look at the top five defenders of the 21st century.#5.
