Location Spain, ground red clay, opponent Americans. Winner is not questionable only the final score IMHO.
The tie is in an empty period after US open. There is a good chance that they will play. From next year there will be ATP points for DC too, at least in 2009 everyone will play.Nadal isn't really consistent in playing Davis Cup, and neither is Ferrer. That said, if those two play it's tough to imagine the US coming out on top.
