Do you really think that Chucho is a better singles player than Gordo* on that surface?
*I mean a "normal" Gordo, not a "shattered" one... You seem to be missing my point. Perhaps I'm wrong, I don't know.
As Vale said Calleri was the better player in the doubles match, second of all. Chucho matches up better with Ferrer than Calleri does, therefore if there is to be a replacement then Acasuso is a better fit than what Calleri is, unless Ferrer is substituted for Verdasco, then this is less clear.
If you want to make a point and not be misunderstood, then come out and say it.
