Deportivo de La Coruna president Augusto Lendoiro is resigned to losing Andres Guardado under the Bosman Ruling with Valencia and Sevilla being linked to the star.
The Galician club are battling to make an immediate return to the Spanish top flight after relegation last term and that has made contract renewal talks with players even harder.
"If we could renew [Guardado's] contract nobody should have any doubt that we would do that," Lendoiro told EFE.
"We have tried to so many times although up until now we have not found any agreement with his representative, Mario Ordiales, but we shall not lose hope that we could do it."
Lendoiro then reflected on rumours that Valencia were set to tie up a deal to sign Guardado on a pre-contract in January or that Sevilla had held talks.
"We cannot give any credence to these things," he continued. "Somebody talked to me yesterday about Sevilla."
"Talks with Guardado are the most complicated of all we have done. With other players we have talked, moved forward and are more less ready to reach an agreement.
"In the case with Mario Ordiales and Guardado there have been greater difficulties."
Guardado moved to Deportivo from Atlas in 2007 after being linked to several major European clubs, including Real Madrid and most of Italy's most glamorous sides.
The 25-year-old Mexico international has made 77 appearances for his country and more than 100 for Depor and now wants a return to top flight football.
