Valencia have already agreed to sell reported Manchester United target Jordi Alba, according to the club's former manager Unai Emery.
The 23-year-old Spain international enjoyed a fine season at the Mestalla and may yet play a prominent role for his country at this summer's European Championships.
Alba has frequently been linked with a summer move away from Valencia, with Barcelona and Manchester United touted as his most likely suitors.
It would appear the Nou Camp or Old Trafford could be the next destination for Alba, after Emery's claims that a deal for his exit has already been agreed.
"Valencia is a team that buys players who are not the finished article and then, when they are finished, possibly sells them on, as has happened with Jordi Alba," Emery told Onda Cero after leaving Valencia at the end of the season.
Able to operate on the left side of defence or midfield, Alba would provide Sir Alex Ferguson with a versatile option and could be recruited as a long-term successor to Patrice Evra.
Barca, meanwhile, were often required to deploy Carles Puyol at full-back last season, and the acquisition of Alba would provide new manager Tito Vilanova with more cover in defence.
