Gary Rowett has confirmed Millwall have lodged transfer bids for targets.
The Lions have won two of their last 16 matches in all competitions.
And Rowett is keen to shake up the complexion of his squad.
The South Londoners are yet to make an addition in the January window.
Asked about an update on the transfer front, Rowett replied: “We’re in a similar position – we’re working really, really hard. We’ve got a couple of offers out to clubs for players and we’ll wait and see if they develop.
“But at the same time we are looking at other options.
“What is really difficult is that no-one wants to let their best players go. It’s the same if someone came in for one of our players. No-one is paying top money for what players are worth because there has been less money in the game.
“Because of that lack of income [due to empty stadiums] it means no-one is going to be tempted to sell their best players.
“The challenge is to try and get the ideal player, but there is a feeling for myself that we might have to move forward and just get some players in – regardless of whether they are ideal ones or perfect long-term ones.
“We need to effect the team in the short term and we need that little bit of a blend of new players coming into the building. We’re working incredibly hard to do that.”
