Men's tennis world number one Novak Djokovic will reveal "never before told" stories about his life in a short documentary series in partnership with Australian winery Jacob's Creek.

"The biggest fight I had in my life was actually the fight within," the 27-year-old said in a short trailer released Monday for the videos called "Made By", Xinhua news agency reports.
 
Djokovic said the mini-documentary form "has given me the opportunity to tell the world my story for the first time, showing what I've been shaped and inspired by".

The video will be released in January.
