The Racing Santander coach admitted this week that there had been "contact" with Valencia, though insisted no agreement had been struck about next season.
However, DiarioSport says Sanchez and Marcelino have already discussed their summer market plans and along with Getafe midfielder Pablo Hernandez, Mallorca striker Dani Guiza and Racing defender Martin Caceres have emerged as top targets.
A host of names are set to be shown the door, with Asier del Horno, Manuel Fernandes, David Navarro, Mario Regueiro, Hugo Viana, Curro Torres and Fabian Estoyanoff among those to be offloaded.
