“It needs time. Nobody wants to hear it, but that’s the truth: if you want to have success in the future, you have to be ready to work now.”

Often, you are forced to keep things simpl

Only stupid people are changed by success.

I was a fighting machine with a will of iron.

The Premier League is one of the most difficult in the world. There’s five, six, or seven clubs that can be the champions.

I’m not a one-man show. I was never that in my life, and I never want to be that.

Sometimes I don’t use the words ‘will’ and ‘want’ in the right way.

Bad performances can happen and are not that serious – even with new players. You can’t, say, sell him, get a new one.

I am not saying I am the best manager in the world. But I’m quite good.

I’m really a normal football manager.

My first win feels better than a draw!

I had no bad moment in my relationship with Dortmund. Not one second.

Yes, it is one of my ultimate aims – it is the ultimate sense of football: to make the people happy, to let them live some emotions that you usually can’t get.

I left Mainz after 18 years and thought, ‘Next time, I will work with a little less of my heart.’ I said that because we all cried for a week.

The wind can be quite extreme in England. We are not familiar with that in Germany, and you have to keep things simple.

If you have never had success, then nobody knows how it is, but in Liverpool, everybody knows how it was.

People should not make me out to be like Jesus; I don’t walk on water.
