Hugo Viana is looking to secure a loan move in Spain, after struggling at Valencia.
The Portuguese international joined Che for (é¼2 million) £1.2 million towards the end of last season.
But the ex-Newcastle United man has failed to secure a regular starting role at the Estadio Mestalla, as Valencia challenge Barcelona at the top of the Primera Liga table.
The club reportedly rejected a é¼6 million (£4 million) offer for the player after the World Cup in Germany, but are now looking to cash in on their investment.
Twenty-three-year-old Viana has been told that he is not part of coach Quique Sanchez Flores' plans and is now looking for a get-out in the January transfer window.
Viana has a contract with Che until 2011 and has dismissed the possibilities of a return to either England or Portugal.
