Tough choice for Kuhnen, given that they play in RA I guess Kiefer is the best choice for the 2nd singles player besides Kohli.
Spain has a choice problem too, I don't know if Nadal plays the tie or not, if he does play the smart choice would be to go with Almagro as the 2nd singles player. Of course Sanchez will never do that and will go with Ferrer based on ranking.
