10. Raphael Varane (Real Madrid)
Signed for over £8million from Lens when he was just a teenager, Real Madrid have got themselves a bargain for possibly the best young defender in the world in Raphael Varane. The Frenchman broke into the first-team this season with some memorable displays against Barcelona, showing great maturity and defensive awareness to shut out Barca star Lionel Messi. Varane is a superb prospect and could attract a big-money offer from Chelsea this summer, as Jose Mourinho is keen to bring the youngster with him to his new club. He already has two caps for France at the age of just 20 and could star for them at next summer’s World Cup, as he quickly establishes himself as first choice for club and country.
