Brian McDermott has not ruled out more players arriving at Leeds before the end of the January transfer window, but suggested he may have to wait until the summer before he can rebuild his squad.
McDermott spoke of his pride in his players after they responded to chastening defeats at Rochdale and Sheffield Wednesday with a much-improved display in Saturday's 1-0 home loss to leaders Leicester.
Leeds owners GFH Capital are hoping to sell a controlling 75 per cent stake in the club this month to Yorkshire-based Sport Capital, but last week blocked a move for Brighton striker Ashley Barnes, who joined Burnley instead.
"We're trying to do something in January, but I've spoken to one of the owners and I've said January is a tough time to do deals," said McDermott after Leicester striker David Nugent's late goal condemned Leeds to a fifth straight reverse.
"You might do maybe a couple of pre-contracts to move ahead to the summer, we're trying to do something now as well.
"But summertime is when you can really build something, that's what I think."
McDermott, who has brought in wingers Jimmy Kebe and Cameron Stewart this month, said the completion of the club's takeover was now their "number one priority", while Leicester provided him with the blueprint for promotion.
"We need to have that stability here, we need to have that," he added. "Those fans, you just feel for them every time you don't get a result you really do because they're incredible.
"I look at Leicester and they've been trying to get out of this league for how long? I can't remember, 10 years?
"They've spent big and (manager) Nigel (Pearson) is building a team and he knows what he's doing, he knows what's happened in the last 10 years, he knows how this league is won.
"You look at Leicester's team and that group of strikers and that is what, in my opinion, we have to emulate - a squad where you know what you're going to get every week."
