Belgrade:US Open finalist Novak Djokovic was greeted by hundreds of fans and Serbia's prime minister on his return from New York.
The welcome party was held on Tuesday at Belgrade's airport with Djokovic, currently No 3 in the ATP rankings, pledging to work on overtaking second-ranked Rafael Nadal.
Roger Federer saved seven set points on Sunday in a 7-6 (4), 7-6 (2), 6-4 win over Djokovic for his fourth straight US Open championship and 12th Grand Slam title.
"In New York I played against mentally the best player in the world," Djokovic said, adding that despite losing he was happy with the final because he managed to win over New Yorkers.
Prime Minister Vojislav Kostunica said that the recent successes of Djokovic and Serbian women Jelena Jankovic and Ana Ivanovic "managed to make Serbia a world tennis power."
Djokovic will lead Serbia in the Davis Cup's World Group playoffs against Australia from September 21-23 in Belgrade.
