Jurgen Klopp has aired his frustration at the possibility of Liverpool being forced into playing during the Premier League winter break.
English football with have a rest period for the first time in February but FA scheduling means clubs could still have fixtures.
Replays for the fourth round of the FA Cup are set to take place during the week the Reds are meant to be on a break.
Liverpool will hope to progress to the next round of the competition by beating Merseyside rivals Everton in the third round tie on Sunday, 5 January.
The Reds are currently in Qatar for the FIFA Club World Cup, playing the final today against Flamengo after beating Monterrey in midweek.
That trip has meant a Premier League match against West Ham had to be postponed with a rearranged date yet to be set.
Speaking to ESPN, Klopp called the decision to schedule FA Cup fourth round replays during the mid-season break as 'incredible'.
"The problem that we have is the Premier League have decided we have a winter break and the FA decided the re-game [replay] if you have to play, if you draw in the fourth round, you play the re-game in that week.
"It's incredible. It's just in the winter break. Right? That's when they set the game.
"Ok, how is that possible? Nobody speaks about these things. I really don't understand that.
"The problem we have now is nobody speaks enough. We don't speak enough to each other so the Premier League, the Football League, the FA, UEFA, FIFA, everyone is planning their own things and nobody follows that so there is no common schedule for everybody.
"Look at that. They are the games, we can't do more games."
The Liverpool manager said the break is needed for the welfare of players but that they need more help from the authorities.
"It sounds like I don't like what I do, but I do. I love what I do, but I know we have two things that are very necessary. There are the players and training," he explained.
"So you can only use the players when they have enough, when they rest sometimes. I know people think that if a player plays, trains two hours a day and plays one-and-a-half hours, that cannot be a problem.
"Other people should try it, because we don't only play. We set our limits a little bit higher.
"We try to do more and do it better and do it quicker and do that. That's like Formula One. At a specific speed, you have to use the brake. That's how it is, because there's a curve you have to use and stuff like this and that's in football the same.
"We would improve this game immediately to the next level if we gave this.
"We try everything -- we give them as much rest as possible, but somebody needs to help us with the schedule and so far that didn't happen.
"The solution I really don't see at the moment. We just have to carry on."
