Watford striker Marlon King is a target for new Fulham boss Roy Hodgson.
King, 27, has netted 10 times this season after missing most of his club's Premiership campaign through injury last term.
Fulham are desperate to bolster their strike force after Sanchez's summer signings, Diomansy Kamara and David Healy, failed to shine.
Director of football Les Reed, who was influential in Hodgson's appointment, is in favour of a move for King - as is first-team coach and former Watford boss Ray Lewington.
