Martin Jol says Fulham have offered a new contract to veteran Mark Schwarzer but are also looking at other goalkeepers.
Schwarzer, 40, has been in fine form for Fulham, keeping seven clean sheets so far this season as the club look to secure a top-half finish in the English Premier League.
The Australia international's deal is set to expire at the end of the season, prompting speculation over his future at Craven Cottage.
Fulham have previously been linked with a move for FC Twente's Nikolay Mihaylov, but the Cottagers' manager Jol has said the Bulgarian is no longer a target.
"I don't deny that we are looking for a goalkeeper," Jol said.
"We are not talking with Mihaylov. Last year we made an approach but not this year.
"We are talking to Mark Schwarzer like we did with Brede (Hangeland) and the other players," he said, referring to centre-back Hangeland, who signed a new contract last month.
"He (Schwarzer) is a fantastic goalkeeper so you would have to be very good to fill that space. We have made him an offer so we are waiting. If he accepts he will stay, if not we will talk again like we did with Brede."
Schwarzer is one of three goalkeepers in the Fulham squad alongside Neil Etheridge and David Stockdale.
It appears the reserve goalkeepers could both be moving on in the off-season, with Stockdale believed to be keen on a move in a bid to secure a first-team role.
"There is a lot of speculation in the press," Jol said.
"I have a young goalkeeper in Neil Etheridge, he is out on loan and so is David Stockdale.
"He doesn't want to be number two so that could be a little problem, so of course we are always looking for a goalkeeper."
