West Brom boss Tony Pulis is "desperate" to add to his squad before the deadline falls.
Pulis brought in midfielder Jake Livermore in a £10m move from Hull earlier this month and has until 23:00 GMT on Tuesday to strengthen his squad.
"There is such a small pool that we are fishing in," said Pulis.
"We're moving forward, but it will take time. We have a budget and we've got to make sure the players are right. We're desperate to bring players in."
The Baggies are eighth in the Premier League, but lost in the third round of the FA Cup at home to Championship side Derby County and Pulis said he has missed out on players that he wanted.
"We've moved up a level this season," added Pulis. "We are competing against teams like West Ham and Everton but players have gone there instead."
