Jurgen Klopp has discussed his long-term future at and eventual exit from Liverpool.
Klopp was appointed Liverpool manager in October 2015, and has overseen gradual improvement at Anfield.
This is the German’s third club of a storied career, having taken over and galvanised both Mainz and Dortmund.
But he does not expect to emulate Friday’s opponent in Arsenal manager Arsene Wenger, and expects to leave the club before two decades are up.
“Stay here 20 years? Don’t know, don’t know,” he said. “So far, after seven years, I’ve felt maybe I should move on.
“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.”
Liverpool’s longest-serving manager, Tom Watson, was in charge of the club for 19 years from 1896.
“It would be quite difficult to become the record coach at Liverpool. I don’t know,” Klopp said.
“As long as it works really, really well, I will carry on. That means as long as there is space for improvement because even if you win something, which everyone here is desperately waiting for, it could be the moment I say, ‘OK, but now we have to leave.’
“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.
“We will see. I don’t feel I am close to that moment and everything is fine.”
He added: “If anyone thinks they can make a career like Alex Ferguson or Arsene Wenger in clubs, I’m not sure it would be possible.
“I think Arsene gets a lot of criticism. I’ve seen it since I’ve been in England and for sure it’s not right, but he’s still there and he’s doing a brilliant job again. Top five, six, fighting for fourth and being involved in different cup competitions and things like that. He’s obviously still very ambitious.”
