Former Northern Island manager Sanchez has been thwarted in his attempts to bolster his attack, with bids for Blackburns Jason Roberts and West Broms Diomansy Kamara failing.
Reports linked Fulham with a move for £4million rated Camara, who managed six goals in 26 appearances, but this has been refuted.
A Fulham spokesperson said: "Fulham have not made an offer to Wigan for Henri Camara."
