Nigel Pearson said he would not rule out bolstering his Leicester City squad before the loan window shuts on Thursday.
City's promotion push has begun to falter after a run of one win in nine league games.
Pearson said if the right opportunity arose, he would consider bringing in a fresh face before their next game against Millwall on Friday.
"The loan window closes on Thursday, before the next game," said Pearson.
"I will have to look at the situation and then discuss whether there are any possibilities.
"There is only one chance now to do it, absolutely.
"Although our form is poor, we can salvage the situation.
"I am not prepared to let this opportunity fizzle out because we have hit a poor run of form.
"There has been a lot of hard work to get into a decent situation, but there is no doubt we are putting our opportunity in jeopardy with this poor run of form. We can't hide from that."
City entered the international break on the back of a disappointing defeat at Derby, and Pearson said he would not argue with suggestions that the Rams showed more desire than his side, certainly in the first half when they took a 2-0 lead.
"We certainly didn't take the responsibility, there is no doubt about that and I wouldn't disagree they worked harder than us," he said.
"That is just not something that is right for us.
"We have worked so hard to get into a good position but, at the moment, we are not playing well enough. We huffed and puffed in the second half but didn't show enough quality.
"To go two goals down and the fashion of the goals – they were two poor goals to concede, we have to rectify this quickly.
"We are putting what has been, for long periods, a positive season at risk by under-performing.
"I am going to have to have a good long look at how we shape up for Millwall because I am not happy with how we went about the previous game."
