10 things that happened the last time Serena Williams was not World No. 1

But Novak Djokovic was World No. 1 … because some things don’t change

Serbian sensation Novak Djokovic is at the prime of his career and with 12 Grand Slam titles already in his kitty, the Serb looks likely to take many more in the coming years.

The 28-year-old, who went pro in 2003, won his first Grand Slam title five years later at the Australian Open of 2008, and with the exception of 2010, has won at least one a year ever since.

By 2013, Djokovic had just under half the Slams he has today – at 5. His consistency and form gave him the No. 1 rank on the ATP World Tour that year again, after he first held it in 2011, and he held it until nearly the end of 2013, when Spanish ace Rafael Nadal took the title for an eight-month period before Djokovic regained the title.

He has held the title ever since.
