Djokovic calm despite shock loss

Djokovic was broken six times by his Serbian compatriot

Novak Djokovic was keen to look ahead after suffering a shock defeat to fellow Serb Viktor Troicki in the second round of the Croatia Open.

Troicki, the world number 176, recorded only his second ATP match win - against the world number three.

But after losing 6-2 4-6 5-7, Djokovic said: "Viktor played a good match and he deserved to win.

"Of course I'm disappointed but you have to turn the page and look ahead after such a loss."

The defeat ends Djokovic's European clay-court season and the 20-year-old will now begin his preparations for the US Open, beginning with the Montreal Masters on 6 August.

Troicki's only previous match against a top-10 player came in the second round in Tokyo last year when he lost in two tiebreaks to Roger Federer.

The 21-year-old will now face Argentine Carlos Berlocq in the quarter-finals of the clay-court tournament in Umag.

"Novak and I have known each other since we were eight," said Troicki.

"I played against him many times, but I only remember beating him once in the under-10s.

"I think that my game is at a good level right now, I'm trying to give my best and I hope that I'll be able to reach the top 50 at some point."
