The 16 time Grand Slam champion and former world no.1 Roger Federer of Switzerland was the first tennis athlete to surpass the 10 million facebook fans. He broke this magic number during the Dubai Duty Free Tennis Championships.
Right behind the Swiss is Rafael Nadal, who can also claim 10 million plus facebook fans to his name. Djokovic has just over 1.7 million likes.
But Nadal is the absolute leader when it comes to twitter, he has got more than 1.7 million followers.
