Klopp has spoken previously about the huge sums of money involved in transfers and the implications it might have for the future of football.
In 2016, the German questioned spending £100m on a player after Manchester United re-signed France midfielder Paul Pogba for a then world record £89m.
"The day that this is football, I'm not in a job any more, because the game is about playing together," Klopp said.
"Other clubs can go out and spend more money and collect top players. I want to do it differently.
"I would even do it differently if I could spend that money."
In April, Klopp compared talk of big-money transfers with "a five-year-old asking for a Ferrari for Christmas".
"We cannot have six players in a summer, everyone for £100m," he said.
"What we need and what we want, we try absolutely everything to get it, but there are moments when you have to accept that this or that is not possible for us - you step aside and do different stuff."
