Klopp is concerned that the domestic football calendar in England is placing too much strain on the nation's top stars.
Now the German has called on the Football Association to take a drastic step. Klopp said: "Replays in the FA Cup? No, have a penalty shoot-out.
"The usual explanation against that is that the smaller teams have a chance to win the replay if it's at home. Then give them the home game in the first place.
"Go there, play there. If they beat us: 'Congratulations. Go for it'. But these kinds of things, replays. It's just another game on television. But who watches these games? That's the place where we have to start."
Klopp is also concerned about plans by FIFA to introduce a 24-team World Club Cup in China in 2021 but knows Liverpool will be attracted to that by the money on offer.
"But the Carabao Cup semi-final two legs is nothing to do with money," he added. "Nothing. It's not OK, These games are not OK. And that's not about money.
"Ask one of the teams involved in the semi-final what they think about the second leg being another game in that period.
"And after that you may win a competition. If you win it's great, if you lose no one remembers you were in the final.
"Yes, it's silverware and that's great. But you pushed the boys and we never think about that. The Football League and the FA have to talk and find a solution, just internally.
"Every year we do the same. We talk about it at this stage of the year and then the rest of the year we don't talk about it.
"We have seven games in a week now and so we start talking about it. So we just talk now because it's that time."
