Valencia's new managing director Javier Gomez cannot rule out cashing in on their stars this summer.
With Valencia struggling under massive debts, Gomez said: "There are many ways to make cash. We'll do what needs to be done. For the moment, however, we think of as part of such costs is to gain credibility with the public institutions.
"Then, from June 30, we will see who could leave."
David Silva and David Villa are regarded as Valencia's most saleable assets.
