Novak Djokovic seems to be enjoying himself at this edition of the US Open.
The world's number one tennis player is the great favorite for the title, in the absence of two giants, Roger Federer and Rafael Nadal.
The Serbian posted a video warming up with a little dance, before facing Spanish Pablo Carreño Busta on Sunday.
An empty Arthur Ashe Stadium was the perfect venue for the "concert" of "Nole" Djokovic.
