I don't mind players earning money, but it should mean, at the same time, that the club is doing good.
Henrik Larsson
Football is all about self-confidence.
I understand that I have to prove myself as a manager. I think I have the potential. I have a lot of knowledge to share, and I think I'm well equipped to translate my thoughts to the players.
You learn a lot about yourself when things aren't going well. It's always good to be the underdog.
If the club is doing good, the club is getting income, then the club can share it with the players. But when the situation is not going according to plan, you have to look at the financial bit and see what you can change.
In England, somewhere. I want to be at a big team, in the big leagues again.
As a manager, it's the same as a player: I want to see how far I can get.
As a kid, I dreamed of playing in a warm land with a swimming pool.
I think the day you underestimate the importance of the job at Celtic Football Club, that's the day when you fail. I've seen a few coaches doing that.
I think, as long as I'm in this line of work, I'm always going to be mentioned when Celtic are looking for a new manager.
The career I had at Celtic, the amount of goals and assists and the relationship with the fans and the club, I can't regret that. That's something I'm going to cherish as long as I live.
You're going to watch football all your life - you're going to watch the Champions League and the Europa League - and I don't have a great feeling when I watch the Europa League, but when I watch the Champions League, I have a great feeling.
Obviously, as a manager, you decide the set-up of the team, who's playing, but when it comes to doing the things I want, I have principles, but I also want to leave it open for the players to find their own solutions. At the end of the day, it's also about the individual.
The thing that is really important is that the players have the drive to do something more with their football. If you have that, you can make a decent player into a very good player.
I'm honoured to train players that want more from their football than just raising their small wages.
I didn't have a clue how big a club Celtic were when I joined.
There are players who tend not to look at the money short-term: they have a bigger plan.
I can't be Martin O'Neill; I can't be any of the other coaches - I have to make my own way.
Everything was professional at United. They really take care of their players.
As long as I am involved in football and doing this work, I am going to be connected to Celtic.
My managerial ambitions were the same as I had as a player: to become as good as possible and to join the big teams in the big leagues.
At Helsingborgs, there were ups and downs, and you need to learn how to handle it.
Moving to Glasgow from Feyenoord was a life-changing experience.
I didn't have to leave Celtic and go to England for money. It wasn't worth the hassle, and my wife and children felt settled in Glasgow.
There would have been no Barcelona, and a lot of other things besides, for me if I hadn't signed for Celtic.
When I was 18, I had a trial at Benfica, when Sven-Goran Eriksson was the manager. Then, at 21, I was working for a company loading vegetables onto trucks.
I was 22, and getting into a World Cup squad is what you dream about as a kid, so finishing third was fantastic.
I had many good managers: Wim Jansen, Martin O'Neill, Frank Rijkaard, and Alex Ferguson, to name just a few.
The dreadlocks were easy to maintain: I got up in the morning and flicked my head. If they got too big, I'd pull them apart every now and again. In the end, I got too old for them.
