Villa, 26, has already turned down moves to Spanish
giants Barcelona and Real Madrid this summer, while Manchester
United are also interested.
Anfield chief Rafa Benitez wants to pair Villa with
Fernando Torres, with Liverpool reckoning their Spanish hitman can
persuade his international strike partner to head to
Merseyside.
After sitting out Saturday's comfortable 2-0 victory
over Cardiff, Villa is expected to play his first pre- season game
in a friendly against Alex Ferguson's new-look United on Wednesday
night.
Emery accepts scouts will be out in force again at Old
Trafford but maintains they will be wasting their time. He said:
"Valencia want to keep David but he also wants to stay. "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. "He is willing to play for us and
everything else is just speculation."
Villa's club colleague David Silva has also been a
long-term target for Benitez, Ferguson and Real Madrid. But Emery
believes Valencia can turn down any offers for either of their star
assets.
He added: "There has been a lot of speculation in
recent weeks but there haven't been any new bids for the players.
"The players are a firm part of Valencia Football Club - and we
believe both of them will stay with us next season."
