World number one Novak Djokovic has said his right elbow is "not in an ideal condition" before the Srpska Open in Bosnia-Herzegovina.

The Srpska Open is the 22-time Grand Slam winner's final tournament before the French Open starts on 28 May.

"I hope it will be fully ready for the first match," said Djokovic.

"I'm super excited to be here because I think it's one of the best places for us Serbian tennis players and athletes in general to be able to perform where we have so much love and support from local people.

"The people welcome me wholeheartedly with a great reception and so much love and support."

Djokovic will begin his quest for an unprecedented 23rd Grand Slam title at the French Open against French 18-year-old Luca van Assche.
