Novak Djokovic on Sunday made history by becoming the first man to win all ATP Masters 1000 tournaments since the inception of the event in 1990.

 Djokovic cruised to a 6-4, 6-4 win over his long-running rival Roger Federer in the Cincinnati final and thereby completing the Golden Masters.

The Serbian who last tasted victory in the ATP 1000 event five years ago in Monte Carlo, held his nerve for one hour and 25 minutes to seal the vital win and extended his head-to-head record over the Swiss to 24-22.

Speaking on court after the match, Djokovic said: "Obviously it's a very special moment to stand here for the first time with the winning trophy here in Cincinnati.

"The hard times I went through, it's been a rollercoaster ride in my career with injury, taking time off and having a surgery earlier this year. This seems a bit unreal to be back at this level."

Federer, the 20-time Grand Slam winner and seven-time champion in Cincinnati, showered praise on Djokovic after the final.

"Congratulations Novak on writing history today. It's an amazing effort not just today but your whole career to get to this point. It's an amazing achievement. You should be very proud. Well done."
