Liverpool could only settle for a point away at Craven Cottage after twice coming from behind, with Darwin Nunez and Mohamed Salah cancelling out Aleksandar Mitrovic's double for the hosts in a 2-2 draw.
Liverpool's inability to take all three points was compounded by the withdrawal of influential midfielder Thiago in the early stages of the second half.
The Reds were already without Naby Keita, Alex Oxlade-Chamberlain and Curtis Jones for the match and Thiago's absence poses a midfield headache for Klopp but the German tactician is not ready for an impromptu delve into the transfer market for additions.
He told reporters: "I know what will now come up, it's clear. We said we don't need a midfielder because we have enough – and we actually have enough, but the problem now is we get punished for something that is not our responsibility really because things like this can happen.
"Nobody could image that Curtis gets the thing he gets; it is nothing serious, but he is a young boy and it is a kind of stress reaction. Bodies are like this.
"Naby is only ill and he will now be back definitely next week again. Oxlade happened early and now with Thiago that is, of course, not good and we will see.
"Look, a transfer must make sense now and in the long-term; we have midfielders, we have still enough midfielders. It is not that we lack midfielders, but it's just some of them are injured.
"This is not a good situation, I don't like it at all, but we have to see how we react on that – but for sure not panicking."
