Novak Djokovic has sealed his successful return to tennis.

The world number one has beaten Kei Nishikori 6-3, 7-5 in the final of the Toronto Masters, a month after his early Wimbledon exit.

Djokovic took just under 90 minutes to secure his fourth Canadian title.

It's his seventh Masters title of the year and record-extending 30th of his career.
