If you play tennis or watch tennis matches you must be knowing whom i will be talking right now. Ofcourse the best three of all time are Roger Federer whom every tennis passionate call GOD OF TENNIS, Rafael Nadal or RAFA and Novak Djokovic.
All of them have 20 Grand Slams each. And hence we can call it as a tennis era. All of them have there own signature shots. Feddy having inside out forehand, Rafa having topspin and my fav Banana shot and Djokovic's backhand down the line. All of them are above 33 years of age and still there fitness is mindblowing.
