Juan Martin del Potro and David Nalbandian will play for Argentina in the April 6-8 Davis Cup quarter-final against Croatia, according to team captain Martin Jaite. “We’ve already thought about lining up Del Potro and Nalbandian on the first day and, all being well, we’ll stick to that plan,” said Jaite. Nalbandian will also play the doubles with Eduardo Schwank. Croatia, captained by Zeljko Krajan, will be represented by Marin Cilic (world number 23), Ivo Karlovic (54), Antonio Veic (166) and doubles specialist Lovro Zovko (92).
