Klopp expressed anger at this year's World Cup adding to players' already hectic schedule, with the tournament ending five months before the domestic season concludes in May.
The Premier League season will be paused from Nov. 12 to Boxing day to accommodate the Nov.21 to Dec. 18 event.
"If you go to the final at a World Cup and win it or lose or a third-place match you are already quite busy and then the rest starts a week later," Klopp told reporters on Friday before Liverpool's Premier League opener at Fulham.
"If all the players then have a break it is not a problem, it is good. It is like a winter break which I had that in Germany as a player a lot, four weeks (off), stuff like that.
"When I start talking about it, I get really angry... It is like with the climate. We all know it has to change but nobody is saying what we have to do."
Klopp added authorities like FIFA, the Premier League and England's FA must put self-interest aside and find a way to ease the burden on players.
"There must be one meeting where they all talk to each other and the only subject should be the most important part of this game - the players," he said.
"My problem is that as much as everybody knows it's not right, nobody talks often enough about it that it will be changed. Something has to change.
"This World Cup happens at the wrong moment for the wrong reasons."
Liverpool will be able to call on first-choice goalkeeper Alisson (29) for Saturday's game but Klopp said his team will be heading into the new campaign with a host of injury issues.
Liverpool have suffered a number of setbacks during pre-season, with centre back (23) and Alex Oxlade-Chamberlain (28) picking up injuries while Diogo Jota (25) and Caoimhin Kelleher (23) reported back injured following international duty.
Alisson, who missed most of pre-season with an abdominal injury, is "fine" to return, Klopp confirmed, adding he is hopeful Naby Keita (27) will return to training after recovering from illness.
Curtis Jones (21) will miss the trip to Fulham with a calf injury, while full back Kostas Tsimikas (26) is expected to resume full training next week.
"We have too many injuries, that's true. But nothing has changed (in terms of transfers)," Klopp said.
"But we cannot solve the problems we have for four weeks with a transfer. At the moment it makes no sense to us. But the transfer window is still open so we will see, but there are no plans."
