India might have notched up a historic 3-1 victory over South Korea to enter the World Group play-offs of the Davis Cup, but India's veteran tennis ace Leander Paes believes India will have their work cut out against fancied Serbia, which could boast of players of the calibre of Novak Djokovic and Janko Tipsarevic.

"A job well done in Korea, but the next tie's (against Serbia from September 12 to 14) going be a tough one," Leander said on the sidelines of an event to launch his own tennis academy Ace Tennis in collaboration with Khar Gymkhana yesterday.
