The 27-year-old Serb was on fire again this weekend when he beat new world number three Andy Murray at the Miami Masters 7-6 (7-3) 4-6 6-0 and extend his dominance over his Scottish rival. He now leads Murray 18-8 after 26 matches.
With the clay court season beginning, leading into the second Grand Slam of the year, the French Open starting on May 25, one has to wonder is anyone going to stop Novak from winning his first title at Roland Garros?
So far his overall record in 2015 has been rather impressive having won 23 of his last 24 matches and notching up the Australian Open, thumping Murray in the final.
Djokovic defeated John Isner and Murray en route to his 21st Masters 1000 title, beating Roger Federer in three sets to win Indian Wells recently.
In Miami, he defeated David Ferrer and John Isner en route to winning his fifth title defeating Murray in the final on Saturday to become the first player to complete the Indian Wells – Miami title sweep three times.
Judging by his record on clay including his nine Roland Garros titles, Spain's Rafael Nadal will in all likelihood be the man to beat to win that elusive Slam.
The interesting thing which makes, Djokovic's chances look better than ever of winning, is that Nadal has not looked himself for a long time after recovering from injury. He simply does not look the man he was and that steal is missing and results have showed this.
On Monday Nadal's world ranking dropped to number five from third place.
Nadal began 2015 as the defending Champion at Qatar, but suffered a shocking three set defeat to Michael Berrer in round one. At the Australian Open crashed out at the quarter-finals losing to Tomas Berdych in straight sets, ending a 17-match winning streak against the seventh-seeded Czech.
He then played at the Rio Open, losing in the semi-final to Fabio Fognini, before going on to win his 46th career clay-court title against Juan Monaco at the Argentina Open. He then has a quarter-final loss at Indian Wells and a third-round loss in Miami.
It will be interesting to see what happens at the Monte Carlo Open starting on April 12 to gauge how much of a threat Nadal will be this clay court season, leading to his attempt to win a tenth French Open title.
Djokovic has come close to winning at Roland Garros, having been runner-up twice and a semi-finalist on four other occasions and with his current form he must be the favourite to win the tournament.
Another factor which has played a big role in the Serbs huge improvement over the last 16 months is coach Boris Becker. Who has been in charge seeing Novak winning his last 10 Masters Series finals in succession including two Grand Slams.
For Djokovic NOT to win Roland Garros he will need to withdraw due to injury or for Nadal to come right and be playing with his usual invincibility on clay, it's as simple as that.
