The answer is: EFC is in far better shape financially than Valencia CF.
Valencia owes loads to the Taxman, the Local Government, and various others with whom it is negotiating. It has 2 stadiums which it struggles to maintain.
The quotation below is from a local rag last month. It states that work at the new stadium is paralysed and that one of its major financiers, Bankia, is desperately seeking a buyer. Valencia alone owes Bankia 306 million euros.
Dos años y medio después de aquel vídeo, las obras del estadio siguen paralizadas y Bankia busca desesperadamente un comprador para
quitarse de encima toda relación con el club. El Valencia C.F. adeuda en total al banco 306 millones de euros.
