Doha: Novak Djokovic eased through to the quarter-finals of the Qatar Open on Wednesday and was then shocked by opponent Horacio Zeballos who took a selfie of the pair on court.
The world number two won his second round match 6-3, 6-4 in just 72 minutes in Doha, thanks to a break of the Argentinian`s serve in each set.
But after the pair shook hands, Djokovic was taken by surprise.
"Making a selfie, that`s the first time I have had this experience in my career," said the Serb. "Horacio - well done, very original."
Djokovic is the defending champion in Doha and this year`s number two seed
Rival, and number one seed, Andy Murray is due on court later on Wednesday.
If the tournament goes to form, the pair will meet in their first clash of the season on January 7.
Djokovic next plays 38-year-old Radek Stepanek after the Czech knocked out Belgium`s Arthur De Greef, 14 years his junior, 6-3, 6-2.
Stepanek is a former Wimbledon quarter-finalist who turned professional in 1996, just four years after De Greef was born.
His victory means he is the oldest ATP quarter-finalist since 42-year-old Jimmy Connors played in the 1995 Halle grass court event in Germany.
Earlier Wednesday, Belgian fourth seed David Goffin, who beat Murray in an exhibition match in Abu Dhabi last week, lost 6-1, 7-6 (8/6) to Spain`s Fernando Verdasco.
