To beat the Fed and claim the mantle of the GOAT, Novak Djokovic would need an almost unthinkable eight more Slams. And like Rafa, he's over thirty and his body is beginning to fail him.
He absolutely loves being a husband and a father. His wife, Mirka, is the first girl that he ever kissed, held hands with, went out on a date with. She has been his faithful companion, friend, counselor, and lover for damn nearly 20 years now, and she has given him 4 ridiculously adorable children who plainly enjoy life on tour. She obviously gets along very well with her in-laws, and she has formed a protective barrier around him into which he can retreat at will.
As I wrote back in January, the day that Roger Federer finally calls it a day will irreversibly diminish the game. In my view it will be the saddest day in the history of the sport- because its single greatest, most talented, most lauded, and highest achieving athlete will no longer be out there to show just how great the game can be.
And the day that the Greatest Of All Time, the King of Kings, says "enough", the sheer mountain formed by his achievements will almost surely never be scaled, by anyone, ever.
For now, though, the King is here to stay. Long may he reign.
