Napoli defender Raul Albiol wants to return to Valencia, according to the Spanish club's sporting director Jesus Garcia Pitarch.
Albiol, 30, left Real Madrid in 2013 to join the Serie A club but is now keen to rejoin the club where he came through the youth academy ranks.
"The situation is in Napoli's hands," Pitarch told Radio CV. "The player wants to come, but he has a [one-year] contract left over there."
Pitarch also said that Valencia, who finished a disappointing 12th in the table and sacked manager Gary Neville soon after he replaced Nuno Espirito Santo in December, have to sell players before they can bring anyone new in.
"If we don't let players leave then it is difficult for us to approach any signings," he added. "I hope big players can come, but it's all dictated by what's on the market. If players don't leave, then it's complicated.
"The best thing would have been if many players had their contracts ending, and we didn't have to pay certain contractual charges."
