As soon as the Novak Djokovic stepped on to the Center Court to play this year's Men's Singles final at Wimbledon on Sunday, he understood why he needed to win a further Grand Slam title.

For the second year running, Djokovic managed to steal rival, Roger Federer's thunder, and chance for an eighth record win at Wimbledon, after almost three hours of nail-biting tennis play.

"As soon as I played the first point in the center court as defending champion this year, I understood why this tournament is so special and understood that this is where I belong. This is a time for me to get a trophy again," Djokovic told CNBC's Carolin Roth the day after securing the title.

"Even though it's the third title, it feels like the first one to me, because it's always so special to win at Wimbledon."

"It's probably my best season. 2011 was so far until now, the best season results-wise. This year has been incredible, with marriage and fatherhood as well. I'm just completely satisfied and a happy person. That's why I think I'm at the peak of my career and my life, and that's why I try to be grateful and nurture every second of it."

Having secured £1.88 million in prize money ($2.9 million) from the match, will Djokovic be just as tactical with his investing?

Djokovic told CNBC that while he works with a team of experts on how to invest properly, he has been trying to be "more conservative" recently.

"In the last five to six years, I've wanted to be more conservative with my investments, and wanted to build up a nice capital." In terms of sector investment, he added he was very interested in sports science and the food and beverage industries.

Is Paris the missing piece?

Despite having won five titles at the Australian Open, three at Wimbledon and one at the U.S. Open, many believe Djovokic's biggest craving is still to win the French Open. While Djokovic admits to CNBC that the title is important to him, he doesn't want to focus all his attention towards the one tournament.

"It was not easy to digest that French Open loss in the finals, but I lost to a better player. I had to congratulate him and move on."

"Over the years, one thing I've learned, playing professional tennis at a high level is to leave it whatever happened behind me and reset and move on."

"I do not want to direct all my attention and focus to the tournament that I've never managed to win. I've had so much success, over 50 titles, nine grand slams, Davis Cup and a medal from the Olympic Games."

"I have a career I've always dreamed of having, I never knew I could achieve so much and I'm still 28 and I want to keep going and hopefully one day, I will be able to win the French Open as well."
