Rodrigo was expected to end the week an Atleti player, but he remains with Los Che.
And Alemany explained, "I have perfect knowledge of everything that happens.
"There was the possibility that Rodrigo could be transferred. Valencia has a certain economic situation. Another thing is that I will not participate in the execution.
"Right now, there is no offer on the table for Rodrigo. I fully understand the decision to sell Rodrigo by the maximum shareholder. Who was offering, now no longer offering; and what seemed like an agreement could not be executed, I have nothing to do with it.
"He is available to train and, at his request, to play on Saturday against Real Sociedad."
Alemany added: "Rodrigo is a player of the first team. Our obligation is to be prepared to go to the market for an important player if Rodrigo leaves. The investment in a possible Rodrigo substitute will depend on the idea of the club owner (Peter Lim)."
