Jurgen Klopp has insisted that remaining at Liverpool for the long-term is unrealistic and he will consider leaving if he ends the club's top-flight trophy drought.
The 50-year-old is two years into a seven-year deal at Anfield - the same length of time he spent at former sides Mainz 05 and Borussia Dortmund in the Bundesliga.
Ahead of Friday night's trip to Arsenal, where boss Arsene Wenger has been in situ for more than two decades, Klopp admits that winning a first Premier League title for Liverpool could signal the end of his spell on Merseyside.
"Stay here 20 years? Don't know, don't know," he told reporters. "A few weeks ago I saw a statistic for the longest-serving coaches in the Bundesliga and I'm the record coach of two clubs - Mainz and Dortmund.
"It would be quite difficult to become the record coach at Liverpool. I don't know. As long as it works really, really well. That means there must be space for improvement, because even if you win something, which everyone here is desperately waiting for, it could be the moment I say, 'okay but now we have to leave it'. That is the moment nobody thinks of doing it, going out at the top.
"So far I think I have a very good feeling for these moments. In both situations, I think it was the right moment for both sides, for both parties, the clubs and me and my coaching staff. We will see. I don't feel I am close to that moment and everything is fine."
Opposite number Wenger last lifted the Premier League title 13 years ago and has won three FA Cups since then.
