Villarreal chief Jose Manuel Llaneza says Italy star Giuseppe Rossi will not be allowed to leave on the cheap.
"To our way of seeing things, and seeing the progress and quality of the player, as well as his youth, there are very few clubs capable of signing this player," Llaneza said.
"Just seeing what he's doing in the Confederations Cup is what he has done since he came to our team. Rossi is a forward of a very high level and a great future.
"Not that today he has a price, but I can assure you that Villarreal would not talk for less than £35 million."
