ATP World Tour commentator Robbie Koenig believes that World number one Novak Djokovic would be at his peak and dominate the world tennis for at least next three years.

The former South African tennis player said that Djokovic would win at least two majors for the next three years, adding that two majors a year from the start of 2015 would give him 13 majors in total, Sport24 reported.

Djokovic clinched his eighth Grand Slam of his career in Melbourne after the Serbian trounced Murray in the Australian Open final last Sunday.

At present, Swiss world No 2 Roger Federer leads the Grand Slam tally with 17, while Spaniard Rafael Nadal is on 14.
