Djokovic celebrates Serbia reaching their first ever Davis Cup semi-final
Serbia reached their first Davis Cup semi-final as Novak Djokovic beat Marin Cilic to give them victory over fierce rivals Croatia.
His 6-3 6-3 6-2 win made it 3-1 to set up a semi against the Czech Republic.
Argentina will face France in the final four after clinching a 3-2 win over Russia in a tense tie in Moscow.
Russia's Nikolay Davydenko beat Eduardo Schwank 4-6 6-3 6-1 6-4 to make it 2-2, but David Nalbandian won the decider, beating Mikhail Youzhny in three sets.
His 7-6 (7-5) 6-4 6-3 victory ended Russia's 17-tie unbeaten home run in the Davis Cup stretching back to 1996.
Nalbandian, who missed much of last season through injury and has been sidelined since April with a hamstring problem, said: "I'm happy with my playing here but I'm not surprised at all, even though I had no official match practice since April.
"I know the level of my playing and I did my best to prepare for these matches."
Despite his win over Schwank, Davydenko was not satisfied with his performances during the tie.
"Though I won today, I'm disappointed with my play this weekend," said Davydenko.
"I was playing much better and with more confidence in my previous Davis Cup matches. I was even thinking of withdrawing today."
In Split, Serbia later made it 4-1 against Croatia as Janko Tipsarevic took the fifth rubber 6-2 7-6 (7-5) against Antonio Veic.
Djokovic said: "This is probably the sweetest victory in my career because this is not just an individual win, but a victory for my country.
"We won in one of the toughest atmospheres against a team that has a lot of success in this competition."
