Unai Emery has warned any club interested in David Villa that Valencia consider the striker 'priceless'.
The Spain international's future has been the subject of conjecture this summer, with Barcelona and Real Madrid both known admirers.
There is also reported interest from the Premier League, with the likes of Liverpool and Manchester United linked with making bids.
However, Los Che remain determined to keep their star man and manager Emery has reiterated that Villa is committed to staying at the Mestalla.
Emery said: "Valencia want to keep David, but he also wants to stay with us. We don't want to sell him because he is priceless.
"Barcelona and Real Madrid have already shown an interest in him but David decided to come back to us.
"That was an unbelievable feeling for the club and we don't believe he will change (for Liverpool or Manchester United).
"He is willing to play for us and everything else is just speculation."
