“The one thing I hate about other managers is waffle that is nowhere near the truth. I would never conduct myself like that.”

I did as well as I could at Newcastle.

Finishing fifth in the Premier League with a great team was a fine effort and we also got to the quarterfinals of the Europa League and nearly got past a Benfica side that went to the final.

It affects people around me, but it was my job to see through that.

I look at Rafa Benitez in his time at Liverpool, he had difficult periods and the same goes for Brendan Rodgers in the same job now.

If you’ve had a bad experience with an agent, you have to move past it.

It’s probably a greater reflection of youngsters from France and elsewhere in Europe.

It (Arsenal) is an English club but not an English success.

Until that issue is addressed, no Premier League team wants to be in the Europa League. That’s the reality, even if some don’t want to admit it.

We struggled with it at Newcastle and we were not alone in that among the English clubs.

It’s important that top clubs don’t lose sight of the fact that it’s the English Premier League and English players should be involved.

You have to have tactical plans to get a deal over the line.

You feel vulnerable when you hear things that are not being said.

I would not want to be the Europa League in the current format, that’s for sure.

You always have to have faith in your own abilities and that has to be evident to your players.

Louis van Gaal is one of the most successful managers in the world.

Manners are good when one may have to back up his acts with his life.

The key to being a good manager is keeping the people who hate me away from those who are still undecided.

What’s more important than who’s going to be the first black manager is who’s going to be the first black sports editor of the New York Times.

As Dortmund manager, I lived in a street, and my two neighbours were Schalke fans. They showed it every day, flying flags!

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

I’m really a normal football manager.

I would go swaggering into restaurants in some ridiculous tramp disguise, challenging them to mistreat me, order the things I was least likely to enjoy, then hurl my plate aside in a fury and demand to see the manager.
