Klopp can't bring himself to repeat the words. "Michael asked if I wanted to talk
and I said: 'No, I have to go.' That evening my wife was waiting because there's a very good German actor, and a good friend,
Wotan Wilke Möhring, in a new film in Essen and we were invited to the premiere. But I walked in and told her: 'No chance. I cannot speak. It's not possible to take me out tonight.' There were all these calls from the club – we should meet in a restaurant and speak. I said: 'No, I have to be on my own.' Tomorrow I'll be back in the race – but not tonight."
Some Dortmund players were so affected they could not sleep after hearing Götze's news. "That's the truth," Klopp concedes. "I called six or seven players who I knew were damaged in the heart. They thought they were not good enough – and they wanted to win together. That's the reason it hurt them so much. But Bayern told Mario: 'It's now or never.' I told him they will come next year. They will come in two years, and then three years. But he's 20 and he thought: 'I must go.' I know how difficult it will be to find a player to replace Götze but, next year, we will play differently. It just takes time."
His first coaching inspiration, Wolfgang Frank, managed Klopp for years at Mainz and they were fascinated by
Arrigo Sacchi's work at Milan. "Even though we were in the second division we were the first German team to play 4-4-2 without
a libero. We watched this very boring video, 500 times, of Sacchi doing defensive drills, using sticks and without the ball, with Maldini, Baresi and Albertini. We used to think before then that if the other players are better, you have to lose. After that we learned anything is possible – you can beat better teams by using tactics."
Klopp
outwitted José Mourinho at the Signal Iduna Park. Beyond the relentless pressing and devastatingly quick transitions that define Dortmund, Klopp found a way to blunt Xabi Alonso and, in turn, Cristiano Ronaldo. The fact that Mourinho has since taken to phoning him regularly is another sign of Klopp's place at the peak of European coaching. But, besides tactical acumen, his ability to connect emotionally with his players is telling.
After he has praised Lionel Messi as "the most unbelievable player because there's no weapon against him when he is fit – no tactic will work", Klopp offers a startling insight. Rather than showing his team videos of Barça at their best, for
displays of tika-taka are scarcely relevant to Marco Reus, the hugely energetic standard-bearer of Dortmund's lightning transitions, Klopp offers them photographs. He highlights the way in which Messi and his team-mates celebrate every goal "like it's the first they've ever scored. It's the perfect thing to show my team. I do it very often. I show them photographs of how Barcelona celebrate. I don't use videos because I don't copy Barça's style. But you see them celebrate goal number 5,868 like they've never scored before. This is what you should always feel – until you die."
Klopp has always been interested in ways of unifying his teams for, as he says: "You can speak about spirit – or you can live it." At Mainz, after he'd led the club to promotion in 2004, he settled on an unlikely pre-season trip. "We took the team to a lake in Sweden where there was no electricity. We went for five days without food. They had to do this [he whistles and, using an imaginary fishing rod, casts off]. The other coaches said: 'Don't you think it's better to train playing football?' No. I wanted the team to feel that they can survive everything. My assistant coach thinks I'm an idiot. He asks if we can train there. No. Can we run there? No. But we can swim and fish!
"When I meet one of those players now, from our 'Special Forces', they tell me what happened in the first and last minute and every story in between. Each night in a ****ing tent, lying on the roots, you don't forget that. We had to find the next island. The first one there had to make a fire and boil some water. The whole time it was raining. Only five hours it was not and then [Klopp slaps his cheek] … a mosquito! How can they live in Sweden? You see the sun and [he slaps his cheek again] you feel mosquitos! But it was brilliant. We were like Bravehearts. You can stick a knife in me here – no problem. We went to the Bundesliga and people could not believe how strong we were."
He was soon known across Germany. His incisive yet amusing work as a television pundit brought him a first flush of fame. More importantly, his outstanding coaching impressed Bayern Munich. "Uli Hoeness [Bayern's president] asked if I would see him. I said: 'Yes sir – I have to ask my mother first but I think it will be fine.' He told me they were thinking of two coaches and I was one of them. Later Hoeness decided on Jürgen Klinsmann. It wasn't too disappointing – for a second division manager to be called by Bayern is not the worst thing in the world."
Klopp was also approached by Hamburg. In the end their hierarchy offered the job to Martin Jol because, unlike Klopp, he wore a suit when interviewed. "I know why I didn't get the job," Klopp says. "They came to my house but two out of three guys wanted me. One of them was not sure. I looked like this [Klopp gestures at his unkempt appearance]. I'm sorry!
"I read it in the newspaper that I'm not the right coach because of these reasons and, also, because my players called me Kloppo. I don't think it's disrespectful. At Mainz, when I started as a coach, the players were my team-mates. The next day I'm their coach. Must they start calling me 'Sir'? Hamburg thought if someone called me Kloppo I can't have their respect. I phoned them and said: 'I don't want to go to Hamburg. It's not possible when you have so many doubts about my character.'"
Hamburg must be cursing their fastidiousness. Klopp, since then, has been
linked to Chelsea, Manchester City,
Manchester United and even Arsenal. He still seems tightly bound to Dortmund – but will this always be the case? "I don't know. In this moment I don't think of anything else. If I went to many clubs now and said: 'Hello – bring me offers', maybe some would start running. But I'm not interested because, for me, this is the most interesting football project in the world. In three or four years, if someone wants me, we can speak. But, for now, this is the best place for me."
Klopp comes from a small village in the Black Forest – "There were 1,500 people there when I left and 1,499 live there now." He is the father of two grown-up sons and his wife, Ulla, is a writer. "She wrote a book for children," Klopp says. "It's like Harry Potter – but it's about football. There's no Harry Potter flying on his ****ing stick – just football." Yet even if Dortmund is not the centre of the universe, Klopp has produced a magical world of football rooted in his normality and good sense.
"I got more in life than I was ever supposed to get – family, money, football. None of my teachers, or my parents, ever believed this would happen to me. So how can this perfect life of mine be spoilt because they take our players? It's better if they stay but I'm not sure we'd be stronger. You need change to make the next step in the team's development. If all these players had stayed I would have to go because there'd be nothing new. If I say 'Go left', they would say: 'You've told us that 200 times – we don't want to hear your voice any more.' That's life – so you need new players. It's not an easy situation but I can handle it. I am an absolutely normal guy but it's not so difficult to find a moment to be their friend or, well, [he grins] teacher."
As he approaches the biggest game of his life, Klopp talks merrily of "a fairytale." But he also points out calmly that, last season, Dortmund did the
league-and-cup double over Bayern, as he predicted. It was their second Bundesliga title in a row. At the start of this season Klopp insisted Dortmund were ready to win the Champions League.
Bayern will be favourites but Dortmund have the support of most neutrals – for it is difficult to resist such an exuberant team and their riveting coach.
"We are a club, not a company," Klopp says, "but it depends on which kind of story the neutral fan wants to hear. If he respects the story of Bayern, and how much they have won since the 1970s, he can support them. But if he wants the new story, the special story, it must be Dortmund. I think, in this moment in the football world, you have to be on our side."
