Novak Djokovic has shared his emotional and mental journey through a letter posted to his website after being crowned Wimbledon champion last week.

The 31-year-old has described the transitional period of becoming a father, dealing with long-term injury setbacks and overcoming vulnerability.

The birth of son Stefan, now 3, has been a huge factor in the Serb finding motivation once again.

"I have imagined and prayed that one day I would win a Grand Slam trophy in front of my child," he wrote. "That dream came true several days ago."

After changing trainers and equipment on multiple occasions, he put a lot of gratitude towards the newly struck "golden balance between tennis, priorities and family".

Djokovic suffered six months out in 2017 with an elbow injury, but believed the big issue was lacking any motivation to play and get back to his desired level of tennis.

"I was trying to find solutions somewhere else and solution was always inside of me.

"I was vulnerable so many times in the last few years. And I am still vulnerable. I am not ashamed of it."

By securing Wimbledon in front of his son, Djokovic landed his 13th Grand Slam title and his first after an emotional and challenging two-year period without a title.

Now ranked 10th in the world, he hopes to see his daughter Tara witness him playing from the stands and clinch another title.

Despite reflecting on a tough couple of years, Djokovic is clearly enthralled and captured in the role of a father, writing: "I am writing this message between nappy change and a dinosaurs book." at the start of the letter.

The happy champion goes on the finish his letter saying, "P.S. Wimbledon grass tasted great once more. I would just add some avocado and it would be perfect"
