Carlos Kameni has flown to London to negotiate a transfer to Fulham.
The potential signing of the Cameroon and Espanyol keeper - a long-rumoured target for the Cottagers - calls into question the future of Mark Schwarzer, who has been linked with Arsenal.
Reports place the value of the deal between £2 million and £3.7 million.
New manager Martin Jol is keen to keep Schwarzer but is preparing Kameni as a backup if he decides to move on.
The club have also submitted a £500,000 bid for 18-year-old Aberdeen midfielder Fraser Fyvie.
