Klopp, who joined Liverpool in 2015 and has a contract till 2022, led the club to the Champions League title last season while finishing a close second to Manchester City in the Premier League, Reuters reported.
“I have absolute energy. But I have one problem. I can’t to ‘a little bit’. I can only do ‘all or nothing’,” he told Germany’s Kicker magazine.
“When I decide that I cannot do it any longer then I will take a break for a year.”
Klopp joined Liverpool after a successful time at Borussia Dortmund where he won two league titles and a German Cup while also reaching the Champions League final in 2013.
Liverpool, which has not won the domestic league since 1990, is currently top of the table with maximum points from three games, two ahead of title rival City.
Victory in the Premier League combined with last season’s Champions League crown would instantly turn Klopp into the most successful Liverpool coach in decades.
“After that year (break) a decision must then be taken,” Klopp said. “But chances are very high that my energy level will then be there once more and that I can then do the job the way I want to.”
Klopp is known for his passion and energy on the sidelines while his excitement has landed him in trouble with match officials in the past.
The 52-year-old has also been repeatedly linked with the German national team and Bayern Munich in the past.
