Jurgen Klopp says he discusses Liverpool transfer targets on a daily basis but he "cannot spend the money" as he hints at frustration over the club not strengthening his squad.
Liverpool are out of form and shorn of confidence after a run of five Premier League games without a victory, which has heightened the club's injury problems.
Klopp took the blame in the immediate aftermath of the league champions' defeat to Burnley on Thursday - a result which ended their 68-game unbeaten home Premier League run.
But the German suggests there is a willingness on his part to find solutions in the transfer window, with Virgil van Dijk, Joe Gomez and summer recruit Diogo Jota among those unavailable through injury.
"Of course someone else is making the decisions, it was always like this," Klopp said when asked to clarify comments he made after defeat to Burnley, where he implied he did not have the final say on bringing in reinforcements.
"If people are surprised about that I cannot change that. The situation we have is we discuss on a daily basis.
"Could we improve something or not? I then make recommendations, but I cannot spend the money. I don't make these decisions, I never did."
Liverpool have only scored once in the league since they took apart Crystal Palace 7-0 to go five points clear at the top of the league table on December 19.
But since then their feared strike force has struggled to reach its expected heights and Klopp is aware a change in approach is required.
Klopp said: "When the things don't work out on the pitch as we want them to work out there is an issue. How I understand it, the issue is I didn't tell the boys clear enough.
"I have to change the way I tell the boys and then they have to change the way we play."
Klopp says he may look to create a 'chasers' mentality within his squad going forward as he looks to secure a morale-boosting victory against Premier League leaders Manchester United in the FA Cup fourth round on Sunday.
"In each bad situation there is a chance for something and I see it that way but I will not do that here," he said.
"I spoke to my players last night, I will speak to them today.
"We have to work on the details."
