LOVELY. Djokovic trains with his son

Novak Djokovic has changed his mindset from being the Serbinator we all knew to a champion that can find a better work-life balance.

The world no.2 is currently preparing for the short American swing (Indian Wells and Miami) where he will try to defend his title.

In the meantime, Nole has managed to post a lovely video where he is training with his fun Stefan.

Fantastic!
