Cash even believes the Serbian has proved himself to be better than Roger Federer at his best.
Djokovic has certainly had the most incredible of years, capturing three of the four grand slams, and securing the year-ending world No.1 spot.
And Cash would not be surprised if he rounds off a breathtaking year in style at the Barclays ATP World Tour Finals in the capital.
With 64 victories and just three losses for Djokovic during 2011, Cash said: ‘I don’t think many people saw it coming.
‘Novak has been phenomenal, winning the Australian Open, Wimbledon and the US Open and getting to the semis at Roland Garros.
‘That puts him right up there alongside the best who have ever played. I feel Djokovic is better than Federer in his prime because he has greater opposition.
‘[Andy] Murray and [Rafael] Nadal are also in great form and Juan Martin del Potro and others are always dangerous. There is more depth to the game at the moment and that gives Djokovic the edge in my opinion.’
