The Liverpool manager returned to the scene of his greatest glories today with a firm insistence his players will have to be at their very best if an emotional homecoming is not spoiled by the club at which he remains revered.
A packed press conference at the Westfalenstadion was attended by 130 journalists – around the same number present as when Klopp brought his seven year reign to a close last May ahead of a short-lived sabbatical.
The spotlight has left Klopp, who won two Bundesliga titles and the German Cup during his tenure, uneasy and anxious for the quarter-final first leg tie to begin.
“If we are not good tomorrow, it will be easy for Borussia Dortmund,” said Klopp. “We have the highest mountain to climb, but it is possible. Let’s hope it is a challenge for both teams.
“It is all about the moment. A lot of things can happen. We need to do our best. Play top, top, top level football and only then will we have a chance.
