Novak Djokovic has achieved something 'simply incredible' in winning his sixth year-end world number one, says ATP chief Andrea Gaudenzi.
Djokovic was all but assured to finish the year on top of the rankings after Vienna last week, although he has now been officially crowed by the APT ahead of a trophy presentation at the Tour Finals later this month.
It is the sixth time the Serbian has won the coveted accolade, tying him with Pete Sampras at the top of the all-time list.
And, as far as Gaudenzi is concerned, it is testament to Djokovic's consistency and quality.
"To finish the year as No.1 is one of the most impressive achievements in our sport, one which requires sustained excellence across the season," said Gaudenzi.
"To see Novak achieve this for the sixth time and match Pete's record is simply incredible, and he continues to cement his place in the history books."
The record will hold extra significance for Djokovic, who idolised Sampras from the age of six.
"Pete was somebody I looked up to when I was growing up, so to match his record is a dream come true," Djokovic said.
