Former Reds defender Agger has been able to speak with Klopp during visits to Anfield.
He recalled, "100 percent. Not only the football, but also the team care. What impresses me most about Klopp is not when I talk to him. It is when I talk to the canteen or the other staff that almost everyone adores him.
"There is a reason for that. They will go through everything for him. If you can get there with that setup, then you have come a long way.
"I cannot help but return to this with Klopp and squad care. Nowadays, there are such great football players in every club at this level, so often the difference is how to motivate your players and staff.
"This is also the case with companies. It's about how to motivate your employees to give the maximum of what they can. If we can manage it, then it will also be a success."
