World number three Novak Djokovic and the unheralded Viktor Troicki swept Serbia to an historic first Davis Cup title on Sunday, overturning an overnight deficit to beat nine-time winners France 3-2.

Troicki, the world number 30, eased past Michael Llodra 6-2, 6-2, 6-3, after Djokovic had crushed Gael Monfils 6-2, 6-2, 6-4 to pull his country level with his sixth win in six Davis Cup singles rubbers this season.

"It's the best moment of my life," said Troicki, who had lost Saturday's doubles alongside Nenad Zimonjic to Llodra and Arnaud Clement, forcing his team to face a nailbiting last day.

Djokovic marked the historic moment by having his head shaved courtside by his team-mates.

"It's history. It's our biggest success as individuals, as a team, as a country," said Djokovic, who had defeated Gilles Simon 6-3, 6-1, 7-5 on Friday after Monfils had given France the advantage with a 6-1, 7-6 (7/4), 6-0 win over Janko Tipsarevic.

On Sunday, Troicki had been called in to replace Tipsarevic in the crucial singles and the 24-year-old delivered in style, hitting 58 winners to Llodra's 32 in the 2hr 13min encounter.
