#1 Sergio Busquets
Sergio Busquets is probably the best defensive midfielder in the world right now. Being tall and extremely clever, Busquets is good at man-marking opponents, tactically sound and a consistently performing campaigner.
He has a great vision, pinpoint accuracy when it comes to passing and is also excellent in the air due to his height. Having stood like a rock in front of Barcelona's defence, Busquet's performances over the years has made him a world-class player.
Having represented Spain in 102 matches, he is one of their key players and is handed the responsibility to keep possession and switch the ball from one wing to the other.
Busquets is also responsible for shielding the defence from opposition's attack in the 2018 FIFA World Cup. His form will be crucial for Spain's success in Russia and will be a key defensive midfielder to watch out for in the World Cup.
