BELGRADE, SERBIA: Juan Martin del Potro and David Nalbandian are Argentina's two nominated singles players and have a mountain to climb if they are to upset defending champions Serbia this weekend.
However, one of them is a former Grand Slam champion and the other seems to play his best tennis when he dons his country's colours, so it might not all be plain sailing for Serbia in Belgrade. The two players discuss what they need to do to get the better of the opposition and how they believe they can do this with Chris Bowers.
Janko Tipsarevic, Serbia's No. 2, confirms that he is over the left leg injury that saw him retire against Novak Djokovic in the quarterfinals at the US Open and admits he is aware of the very real threat that the visitors pose to the defending champions in this semifinal clash.
Captains Bogdan Obradovic and Tito Vazquez also discuss their strategies in team selection for this weekend.
Novak Djokovic also praises Davis Cup for giving him the energy to record his winning streak and the catalyst for a remarkable 2011 season.
