Argentina captain Tito Vazquez has yet to decide who will play singles alongside Juan Martin del Potro in the Davis Cup final, which begins on Friday. He has also yet to choose a doubles team. The Argentine press reports that the second singles spot will go to either Juan Monaco or David Nalbandian, a Davis Cup veteran, but a player who is frequently injured. Vasquez apparently is considering saving Nalbandian for doubles and the final day of singles.

Vasquez also has to name his four players by Thursday and will choose between Juan Ignacio Chela and Eduardo Schwank for the fourth spot. Nalbandian and Schwank have been practicing doubles together.

While the Spanish team of Rafael Nadal, David Ferrer, Fernando Verdasco and Feliciano Lopez are favored at home in Seville, Del Potro thinks that Argentina has a chance to avenge their 2008 loss to Spain when they played the final in Mar del Plata, Argentina.

“Spain is the strongest clay court team in history," Del Porto told reporters. "But in Serbia [in the semifinals] it seems like we would need a miracle and we ended up winning.”
