Fulham boss Martin Jol is keen to find four more signings this month.
The Dutchman wants to keep his dealings on the quiet.
"We're talking and doing everything behind closed doors," he told the Fulham Chronicle.
"Hopefully we can present the fans with a couple of good players."
He added: "We got Mladen and Rodagella in, but we need at least one [striker], maybe two other ones.
"We also let Danny [Murphy], [Marcel] Gecov and Dickson [Etuhu] go, all defensive midfield players.
"We've got [Mahamadou] Diarra and Steve Sidwell, but we need one or two midfield players."
