STEVE Lomas says the financial gulf between the Championship and League One is making it difficult for Millwall to offload their fringe players.
Lomas has to trim the Lions' wage bill before he can bring in any more signings, with a new right back and a left winger top of his agenda, but admits little progress has been made on outgoing deals.
Clubs in the third tier can only spend 55 percent of their turnover on wages, thus making it harder for them to afford Championship players.
Lomas said: "We'd like to [bring in more players], but unfortunately from my point of view there were 18 players signed up when I came in, so the vast majority of the budget was tied up. We'll have to speak to the chairman and see whether we can get a few out as well.
"The problem is, where do these boys go on their current contracts? If they go to League One, we would be lucky to recoup 50 percent of their wages. That's the dilemma.
"But this was something I knew about it, so we've just got to get on with it and try to move a few out – maybe we can create some finances to bring in a few more of my players.
"Hopefully there will be a bit of movement towards the end of August but it's very difficult when players are on Championship contracts and the clubs that want them are in League One. They don't want to pay their full contracts so that's the tough part."
