Fulham are looking at alternatives should they fail to agree personal terms with main target Cedric Soares of Arsenal.
Norwich's Max Aarons, Danny McNamara of Millwall and Luton's James Bree are all under consideration with Marco Silva keen to strengthen his right-back options before the window closes.
The Fulham boss is eager to add to his squad depth this month but he is also not willing to pay over the odds to do so - hence why a move for Cedric may collapse.
Arsenal are keen to sell Cedric given he is largely surplus to requirements at the Emirates Stadium - with Ben White and Takehiro Tomiyasu preferred options.
