Gary Neville does not believe dipping in the January transfer market is the answer to Valencia's woes after they suffered another La Liga defeat.
Valencia were beaten 2-0 at Real Sociedad on Sunday as Neville's wait for a first league win continued.
"I want to play with these players so they can improve together," Neville told reporters.
"It's not that the club doesn't want to spend money. There have been some important signings and my job is to get the players to perform.
"I believe I have some excellent players and I assume responsibility for the defeat."
"Everyone in the dressing room is disappointed, myself more than anyone, but tomorrow everything starts again", Neville added.
"I can't sit here without saying it's not a blow.
"We lost against Villarreal [last month] but I was happy with our second-half performance. Today I can't say that. We played below expectations and we have to start winning regularly."
