Pako Ayestaran has insisted that neither Shkodran Mustafi nor Paco Alcacer are up for sale during the current transfer window.
The German defender has been strongly linked with Arsenal, while Alcacer's name has come up repeatedly in connection with a move to Barcelona.
Valencia need to sell in order to meet Financial Fair Play regulations, but their coach is adamant the pair have a future at the Mestalla.
"Mustafi is not for sale and will not be leaving the club," he told reporters following a 4-2 home defeat to Las Palmas on Monday to start the team's La Liga campaign on a negative note.
The Arsenal target did not start in the defeat, heightening speculation he may be leaving for the Emirates.

Ayestaran, however, clarified before kick-off that his omission was due to his fitness, and he came on at half-time with Valencia already 3-2 down.
Alcacer, meanwhile, played the entire 90 minutes, and his coach said he had been told the forward was not for sale either.
"With Alcacer I can be as firm as with Mustafi, [club president] Lay Hoon already said it," he added.
"The president has said in public that Alcácer and Mustafi are not for sale and I have to believe her".
