He made a footage, so all of his followers can see the way he is preparing for next challenges in Paris where he will play in first round against Granollers.

The clip he published, the best Serbian tennis player waits for the signal on several devices, and then he touches them with his hand.

It is, we presume, some sort of exercise for concentration which can be crucial in a fight for every point.

Little Stefan is with Novak, who ran into the video and asked with tender voice:

- Dad, what are you doing? - the boy was wondering.

- I am practicing - Novak said and then dedicated his entire focus to the mental training again.
