World number two Novak Djokovic has said that winning an Olympic gold medal would be as big an achievement as claiming a Grand Slam.
The 25-year-old, who has won five Grand Slams, took a bronze at his first Olympic Games in Beijing four years ago.
Speaking of what a gold medal would mean and the disappointment of losing in the last four at Wimbledon, the Serbian said: "First of all, it's not a disappointment playing semi-finals. Second of all, it would mean a lot to me.
"Of course, it would be probably right up there with all the Grand Slams that I won because I'm playing here for my country in the first place.
"That's something that we as tennis players don't get to experience too much because we're individual athletes."
Djokovic continues his bid for a singles gold medal against Australian veteran Lleyton Hewitt later today.
