Valencia legend Santiago Canizares has called for Gary Neville to resign.
Los Che are reeling after their 7-0 Copa thrashing at Barcelona.
Canizares, who played for Valencia in two Champions League finals, was scathing of Neville, saying on Twitter: "I expected the coach's resignation, as well as some apologies. I may be ignorant, but I'm surprised he hasn't done it, I thought he was honest.
"If (Jesus) Garcia Pitarch trusts in Gary as he said on Monday, I'm disappointed. If it's not like that, why did he say that?
"If (Garcia Pitarch) lied to us, and tomorrow he proposes the sacking of the coach and it's not accepted, it's best if (Garcia Pitarch) leaves as well.
"Worse than the loss, is giving up in the fight. We are facing a test of fire. To demand decisions is responsible, to give up isn't."
