1. Real Madrid | Fans: 717,000
And in pole position sit Barcelona's arch rivals, Real Madrid.
Los Blancos boast a massive 717,000 fans on FIFA 14 - which just goes to show the nine-time European champions' universal appeal.
Real Madrid also, of course, have arguably the world's best player in their ranks: the prolific Cristiano Ronaldo, who looks set to win the 2013 Ballon d'Or next month.
