However, the manager says Liverpool's apparent inactivity in the transfer market since last month's £36.9million capture of Mohamed Salah is down to clubs being reluctant to sell rather than a lack of funds.
Asked if he's happy with the backing he's had from FSG, Klopp said: “100%. What else could I say? If they could make it quicker, you can imagine they would be here and trying. It's not about money or something like this.
“Okay, I didn't ask if I could buy Ronaldo or the other guys from Barcelona but I am absolutely fine with this."
Liverpool are shopping at a higher level this summer and getting business done has proved more difficult.
“It is always complicated, if you want," Klopp continued. “If the (selling) club needs the money or has another solution then the chances are higher, especially in England.
“I read in Germany that there are still transfers in the Bundesliga for £5million. You can imagine that happening in England? No chance. Yet it is similar quality.
“As I say, money is only somewhere else. You are in a circle and that is how it works here. It's not that we don't want to spend. It is all about doing the right things.
“What is the challenge? To convince the players or the challenge to have the money? We pretty much have all what you need but at the end it is still business.
“You go out and see the car that you have been dreaming about your whole life. You say 'here is the money' but they say to you 'I don't want to sell the car.' You say 'but I have got the money!' but they say 'I don't want to sell.'
“Things like this happen in life, not only football. It is not about this. They say 'go for another car in another colour' but you say 'that's okay but I want this.'
“It is pretty simple. You can imagine how it works. It is not that we are doing something that other clubs are not doing or we are more silly or they are more smart."
