MUMBAI — Novak Djokovic's domination of 2016 is not as inevitable as it might appear, former British number one Tim Henman believes, even if the other members of the "Big Four" will have to raise their game and hope the Serbian falters.
Djokovic won 11 titles including three of the four majors last year and has a 12-0 record this season, having thrashed Rafa Nadal, Roger Federer and Andy Murray to win the title in Doha and a record-equaling sixth Australian Open crown.
So impressive was the 28-year-old at Melbourne Park that many pundits believe a first calendar year grand slam in the men's game since Rod Laver in 1969 is on the cards.
