Claudio Ranieri has admitted Fulham must sign an experienced 'leader' in order to avoid Premier League relegation.
Fulham have won just three matches in their 21 outings on their top-flight return this term, with Ranieri replacing Slavisa Jokanovic at Craven Cottage in November.
Chelsea's former England defender Gary Cahill has been linked with a loan move to Fulham, and Ranieri has conceded the Cottagers need to strengthen this month.
'I think we have to sign somebody to survive,' said Ranieri.
