Novak Djokovic hasn't always been the successful player he currently is with the World No.1 speaking to Vasek Pospisil recently on his podcast speaking about his first tennis tournament.

Djokovic spoke about playing Viktor Troicki back then and said he cried when he was smashed 9-0 by his compatriot in the second round.

"I remember the first tournament that I ever played in my life, the first competition I had officially. I was 8. So I won my first match ever 8 all, tiebreak 10-8. I was obviously filled with joy, and I was very exhausted.

My mom was there; she hugged me. And at some point, after she hugged me, I started crying. Then, the next day, I lost to Viktor Troicki like 9-0, and then I cried again. So I cried pretty much a lot when I was a kid" - Djokovic said.
