Manager Dennis Wise is desperate to strengthen his Leeds United squad before the transfer window closes at the end of the month.
The Whites have won all three of their league fixtures this term to wipe out nine points of their 15-point deduction, but Wise wants to keep the momentum going.
He told the club's official website: "It's a very important week. I need some players in.
"I'm playing with two centre-backs - they've both done really well, but I need some competition and there are other things we're looking at.
"The whole bunch we've got here have done great, but there'll come a time when there are injuries and suspensions.
"I don't really like signing loan players, I want players permanently. We have put offers in for players and we're still trying."
