Valencia striker Alvaro Negredo admits relegation cannot be ruled out.
Gary Neville's Los Che again lost on Sunday to Real Betis.
Negredo spoke to reporters in the mixed zone afterwards, admitting:"I must apologise to the fans.
"There is no fear of relegation, but it is there..."
He added: "The team is pretty messed up, the situation is not good for anyone, not for the fans and for us, we are in a bad dynamic and things are not going well.
"Staying together is the only way out of this."
