Novak Djokovic is optimistic of starting for Serbia against Kazakhstan on Friday in their Davis Cup World Group first-round tie after dealing with an infection in both eyes.

The world No.1 developed the problems last week in Dubai, where he was forced to quit his quarter-final against Feliciano Lopez.

Reports indicated that he could have picked up his case of conjunctivitis during a photo shoot in a water park swimming pool 10 days ago.

“All is going well regarding my recovery and I am optimistic about playing in the tie,” Djokovic said.

“I was very sceptical about playing at first, but I still have two days left to adapt to the light and other indoor conditions and hopefully I will be OK.”

Serbia are keen to try and repeat history after winning the worldwide team competition in 2010, with Djokovic leading the effort.
