Speaking to the media, Klopp said [via ESPN]: "I don't know exactly why nobody believes I probably will not be a manager again. But I understand because obviously, it seems to be a drug - it looks like that because everybody comes back and everyone works until they are 70-something.
"I always had the idea that I would not do that that long. Look, other people are smarter, other people can do it in different ways. I have to be all-in, I have to be the spark, I have to be the energy, I have to be all these kinds of things and I'm empty. That's it.
"My biggest worry today was that [goalkeeper coach] John Achterberg was coughing all the time next to me and I thought I would wake up and I'm ill because he did his coughing in my direction!
"I have to start with the rest now and then we will see. But it's not now that I feel already and [think about] maybe the next opportunity.
"You only have to look outside which clubs are obviously available and stuff like this. There will be opportunities, but I don't sit here and think, 'Maybe in a year's time I take that.' At this moment, it's see you later.
"I love all and everything about the club, but it's time for me to go. But look, it's not burning behind me and that gives me a good feeling."
