4. Raphael Varane
Zouma and Varane. French football could have a new defensive axis to rival the Thuram, Desailly, Lebeouf golden age of the late 90s, early 00s.
A mainstay under Jose Mourinho last season, Varane has found first-team football harder to come by under Carlo Ancelotti. Despite just four La Liga appearances, he remains one of the world's best young talents.
Thrown into El Clasico earlier this year aged 19, the Frenchman barely put a foot wrong up against Leo Messi and Andres Iniesta.
Tall, strong and composed in possession, Varane edges Zouma on this list on account of his Champions League and international experience.
