World number one Djokovic insisted that it is possible to win all four Grand Slams in a single season.

“I think anything is achievable. If you believe in it, if you, you know, dedicate yourself to it, why not?”, Djokovic said, when asked if he could achieve the Grand Slam in 2016.

“It’s still very early for me to talk about the Grand Slam in a year.  You know, that would be something very extraordinary, but it is possible. I definitely have that kind of mindset” Djokovic added.
