Wasn't too sure where to put this but I thought this excerpt from a Sid Lowe interview with Kevin-Prince Boateng was great
‘Klopp is the best coach in the world’
But footballers have to play and opportunities remained limited until Dortmund took Boateng on loan for six months in January 2009, the eve of their explosion. The manager was Jürgen Klopp and the mention of his name excites. “Yes!” Boateng says. “I could see it immediately. He’s the best coach in the whole world. He knows when to push you and when to comfort you. He knows when you need a drink, when you need water. He has this …” His voice trails off. “He has everything. Ask the players and they’ll say: ‘He’s the best, I’d die for him.’
“He knows exactly what every player needs and gives them time. There were players at Dortmund who played five minutes in six months but they were happy: happy to come to training, happy to work, because he made you feel important. Not necessarily as a player – maybe he doesn’t need you – but as a person. That’s why he’s successful everywhere. And Liverpool’s perfect; just watching his presentation you see it. ‘The normal one’: people there love that. If he’d gone to Paris, it would have been best suit, [different message]. He knows how to grab people.”
Moments, chance, decisions; they can change a career, a life. There must be times when Boateng thinks: “If I’d stayed at Dortmund with Klopp …” The response is immediate. “I’d have played a Champions League final, won the league, the cup. But: ‘if’, ‘when’ … I don’t know. I’ve had a career many dream of. I’m happy, but I know I could have done better; if I’d focused more, worked harder earlier. I’m happy to have met Klopp, to have worked with him, even if it was only six months.”
