Allardyce watched on Saturday as his side were beaten 3-1 by former club Newcastle, a result which saw them return to the relegation zone.
And, when asked afterwards if 23-year-old Traore would be signing, he said: ‘It’s unlikely.
‘We’re finding it extremely difficult (to bring players in).
‘We had a terrible day yesterday (Friday) when I thought a player was signing for us and then I found out he wasn’t.’
Allardyce also ruled out a loan approach for Arsenal defender Thomas Vermaelen but admitted it was his side’s weakness at the back which cost them against Newcastle.
The Magpies cruised into a two-goal lead courtesy of strikes from Yohan Cabaye and Loic Remy before a Mike Williamson own goal in stoppage-time halved the defecit.
The Hammers did threaten parity after the break but Cabaye made sure of the away win with a late free-kick.
And Allardyce went on: ‘Our defensive frailties were exposed in the first half and unfortunately a spirited fight back in the second half hasn’t got us anything.
‘But we’ll keep our chins up because we’ve got 16 games to keep ourselves in the Premier League.
‘There comes a time when the players have to realise that it doesn’t matter about performances any more and it just becomes about results.’
