"It isn't easy for anyone up against a team like us.
"Valencia's situation is not pleasant, not even for us.
"I do not like to see opponents in this situation. We're just doing our job.
"Every situation has to change eventually and I am sure they will get out of this because it is only a sporting problem."
Neville's side are 12th in the league table and face an away trip to Real Betis on Sunday.
