Having watched his side's opening day win over Malaga from the bench, uncertainty has surrounded the Spaniard's future with Arsenal reportedly keen on securing his services.
The 26-year old has progressed through the ranks at the Mestalla and club president Amadeo Salva insists that Guaita would only be allowed to leave if he requested a move.
"Guaita is a world class keeper and Valencia has no need to sell. To allow him to go, we would have to study the price," Salva told Spanish newspaper Las Provincas.
"Currently the value is 30 million euros (£25million). At Valencia, what you want is to continue, although his agents have reported that if you are a substitute, had better find a way out.
"Just this last point does not sit well in the board. Players can not fall into that temptation to go after every game with this type of attitude.
"If you do not play every week, you have to respect Valencia more."
