Valencia are understood to have identified Villarreal striker Nilmar or Sevilla's Alvaro Negredo as the top targets to replace David Villa, should El Guaje depart in a big money transfer.
Los Che's technical secretary Fernando Gomez is understood to have identified the duo as potential replacements during the summer, according to Super Deporte, but changes at the helm at board level and a lack of a sufficient offer for Villa quelled their interest in the two strikers.
In the case of Negredo, Valencia saw him as a part of a cash-plus-player deal with Real Madrid but with the 24-year-old having made the switch to Sevilla, Nilmar has come into focus as the preferred option.
Valencia have already conceded that they may have to part with Villa for economic reasons and have put a cap of €15 million on the cost of replacing their star striker.
So far this season Nilmar has scored five times in 14 Primera Liga outings and has scored six international goals in five games for Brazil.
With Nilmar having cost Villarreal €11 million during the summer, it is likely that Valencia will have to meet their own limit if they are to renew their interest in the Brazilian.
