Novak Djokovic is playing Monte Carlo with a wrist problem after injuring it last week.

The telltale sign was a strip of blue physio tape running up under his wristband and forearm. Despite the injury, Djokovic managed to win his opening-round match against Albert Montanes in just 45 minutes.

"I have a certain problem that I carry for the last week or so with the wrist. The short match today helped definitely. So I'm going to have some time to heal it," he said afterwards.

Asked about the problem, the Serb said, "I prefer not talking about it. It's just something I carry for the last seven days."
