Udinese president Giampaolo Pozzo has told interested clubs the price for striker Fabio Quagliarella.

"The value is £20 million, just like (Juventus signing) Diego. We have played Werder Bremen in the UEFA Cup and the fallout was that Quagliarella was equal if not better than the Brazilian, so the value is the same," said Pozzo.

Napoli and Juventus are among Serie A rivals keen on Quagliarella.
