9. He is a good impersonator
His amazing skills on tennis court as he won insane points are not the only reason why we enjoy watching Djokovic. He is also a born-showman!
His other nickname is The Djoker. It came up after fans and journalists realized how funny he is on and off court.
One of his comedy tricks is impersonation. From time to time, he would pull off some impersonations of other tennis players even in front of each other. Some of his hilarious impersonations are Maria Sharapova, Andy Roddick, Rafael Nadal, John McEnroe, Guga Kuerten (as seen on the picture), Boris Becker (his coach) and many more.
Unfortunately, as things get more serious on court, he does not do these impersonations as often anymore. However, he still entertains us with his winning celebrations.
