Novak Djokovic remains set on more success after surpassing Steffi Graf's record for weeks spent at world number one.

On Monday, Djokovic celebrated a 378th week as the best player in men's tennis, which overtook the all-time record (for men or women) set by Graf.

Like Graf, Djokovic has won 22 grand slam titles, though the 35-year-old remains in the hunt for more glory.

After his Australian Open triumph earlier this season, Djokovic will be hoping a 94th ATP Tour-level title comes his way at this week's Dubai Tennis Championships.

"I still want more achievements," Djokovic said ahead of breaking Graf's record.

"I could not have imagined this, I was dreaming as a kid to be Wimbledon champion, to be number one in the world. I achieved those dreams in 2011.

"After that, I wanted more. Of course, I'm driven by the goals. I'm as dedicated to the sport really as anybody else.

"It's surreal in a way to be that many weeks at world number one, to match Steffi Graf, who is one of the all-time greats of our sport. Just being among these legendary names is flattering. I'm very proud."

Djokovic's campaign in Dubai starts against Tomas Machac on Tuesday.
