Novak Djokovic is still riding high after his ATP Cup and Australian Open wins. So he's back home, and spending some time on the practice court with a talented youngster you might have seen before.  

Mihailo Topic is a 10-year-old Serbian trying to become the next Djokovic. The junior also hung out with Djokovic's coach Goran Ivanisevic. 

Djokovic must see a lot of himself in Topic:

The world No. 1 was recently featured in a throwback to the ATP Challenger vault. He won two ATP Challengers in 2004, in Budapest and in Aachen. 

Djokovic is next scheduled to compete in Dubai, which starts in a week.
