"We are here now and we are completely focused on it, but if you had asked me beforehand if I think that there should be a Club World Cup in the middle of our season, I would say no, in my honest opinion," Klopp told journalists at the Khalifa International Stadium in Doha, where Liverpool faces Monterrey on Wednesday.
The Anfield club has had to take time out from its seemingly relentless march toward the Premier League title to travel to Qatar for the tournament, in which it is Europe's representatives thanks to its Champions League triumph last season.
If Liverpool wins against the Mexicans, it will advance to a final on Saturday, while even if it loses its semifinal it will remain in Qatar for a third-place playoff at the weekend.
Reds’ Premier League trip to West Ham United, scheduled for this weekend, was postponed as a result, and they were forced to play their League Cup quarterfinal at Aston Villa on Tuesday with a squad of academy players due to the lack of alternatives in a packed schedule.
After the competition concludes, Liverpool will rush back home to prepare for a trip to Leicester City – its closest title challenger – next Thursday, on the Boxing Day holiday in the UK.
FIFA recently confirmed plans to expand the current seven-team Club World Cup played in December to a 24-team competition which will start in China in 2021 and will be played in June and July – that means a clash with the next Africa Cup of Nations, to be held at the same time.
The existing format is particularly unloved in Europe, even if European clubs have won the last six editions.
Klopp added, "Can it be an even bigger tournament in the future? I don't know. We have to make sure that we have great competitions, but not at the same time, that's all.
"I like now being here because we have a lot of fans in this part of the world, they usually have to follow us at night time if they want to watch our games so that's nice that we can come closer from time to time.
"But everybody needs to think about it. If there is time for a tournament which is nice, then you cannot have then another. You cannot just add on tournaments, that doesn't work."
