New era is good for tennis - Djokovic

Novak Djokovic believes his ascendancy to the number one spot and the rise of Andy Murray's form is part of a new era in men's tennis, following Roger Federer and Rafael Nadal's domination, which is good for the sport.

Djokovic is the first player, other than Nadal or Federer, to hold the world number one ranking since 2004.

The Serbian also reveals kneeling to eat the grass on Centre Court will become a tradition should he win Wimbledon again.
