Neustedter played for Klopp at Mainz and says the German's man-management is key to his success.
He explained to Sport-Express: "All the players are delighted with him.
"So it was in my time at Mainz and now it's the same, judging by the interviews of the Liverpool men. Klopp learns, develops. The most important thing, in my opinion, is that the substitutes feel part of the team, they are always ready to enter the field.
"For example, (Divock) Origi appears almost always only for a replacement. But as soon as he gets into the starting lineup, he immediately scores. This is the strength of the German coach."
Neustedter also said: "How Klopp selected a team, how he prepared for the matches - it was immediately clear that this was an unusual coach.
"The eyes were on everyone: those who went on the field, those who remained in the reserve, those who did not have a place in the squad.
"For Jurgen, you were ready for anything, you just had to win."
