Jurgen Klopp says his ­Liverpool players have ­rediscovered the mentality of champions.

And the Kop boss has challenged them to maintain that mindset through what he calls “the slog” ­between now and Christmas.

Klopp’s side are the only team in all four ­divisions of English football to boast a 100 per cent ­record and the German says that is no accident – his ­Champions League winners planned to hit the ground running.

“Oh yes, we knew how ­important that would be,” Klopp said.

“We were criticised about our pre-season and we were not good, that is the truth, but it was my fault that we had heavy legs. My priority was to be ready for the new season.

“It wasn’t about playing the best football, but winning the (first four) games. I’m so pleased we have done that because it was really difficult to be ready given that four or five players came back from their summer break only in the last 10 days.

“But so far it has worked.”

Klopp says the first month of the season is about laying the foundation for what comes next. And what comes next will really challenge his side, who finished runners-up in the Premier League last term with a record haul of 97 points

Starting with Newcastle today and a European trip to Napoli next week, the Reds have two games a week right through until January.

Klopp, who delivered a first trophy for Liverpool last term, said: “It always felt like we were one step behind until we finally won something.

“Now we have and it’s a big relief.

“We’ve had a good start too. Against Arsenal (Liverpool won 3-1) and Burnley (they won 3-0) we were exceptionally lively.

“That’s special but it’s done now. We have to be 100 per cent focused - that’s what took us to the position we were in last year.

“And as long as we can keep that mindset alive, it will be good. Yes, we have quality, but only with this mindset can we really perform on the pitch.”

Between now and October 5, just three weeks away, Liverpool will play seven times.

Klopp knows the next two months will be vital to his side’s crusade to lift the title after a 30-year wait. Last term they finished just a point behind champions Manchester City .

“The next few months are the most intense – right through until January,” he said. “It’s a slog.”
