Djokovic laments Federer's absence in Dubai

Novak Djokovic admitted on Sunday he will miss injured rival Roger Federer as he prepares to begin his charge for the Dubai Championships.

Swiss defending champion Federer was forced to withdraw after this week undergoing right knee surgery which will reportedly keep the 20-time Grand Slam winner away until the summer grass season.

"It was a surprise, to be honest," Djokovic said prior to his Monday start against Tunisian wildcard Malek Jaziri.

"I knew he was struggling with an injury in the Australian Open. But no one knew really what was the injury, what is the extent of that injury.

"I really don't like to see anybody going through surgery. I've been through that once, and hopefully the last time in my life.

"Roger is Roger -- this sport needs him."
"There's also a very big Serbian community here so big support on the stands. Can't wait to kick off."
