Fulham are eyeing VfB Stuttgart striker Serhou Guirassy.
BILD says Nottingham Forest and the Cottagers are in contact with Stuttgart for Guirassy about a January deal.
The centre-forward has a 20m buyout clause which can be triggered next summer.
The Swabians are now in talks with Guirassy's management about trying to increase the clause in exchange for a higher salary.
The original plan was to completely buy out Guirassy's clause. However, the player has refused such an option.
