The World Cup is the biggest party in football and it's a party for the world, it's incredible. It goes for a month and there is a huge amount of interest. It's the greatest thing you can do and it's beautiful.
I liked friendly games, but I took them like a test to test new players. People didn't like that very much.
England was the biggest coaching job that I had. You know, in England, the football is connected to all the things in a incredible way. I'm very proud to have been there.
My worst moment was in 2006, in Germany, without any doubt! The defeat in the knockout phase of the World Cup 2006 against Portugal.
China, if they decide to do something, they do it. Not only in football but whatever it is. If you think about the billion population, there must be Messis or Ronaldos out there. There must be many talented football players out there.
To be a manager, you have to perform always. You cannot live in history. It's now and tomorrow that counts.
It's not that India, China and the United States need football, but football needs these three countries. Because it will be even bigger.
If you want to keep up with the changes, then you have to watch as much football as you can. Live is the best way but also on television. All the best teams: Barcelona, Real Madrid, Bayern Munich and now City. What are they doing? If possible, go and see them training. You can always learn.
My second year in Rome was very good. Back then, a striker was a striker. Strikers scored goals; they didn't defend. Today this is normal, but it wasn't at that time. If you wanted to play my style of football you couldn't have old players or famous players who were unwilling to do the job both ways: attacking and also defending.
After three years with Roma, I spent two seasons at Fiorentina. I could have stayed there for longer, but they only had ambitions to be in the middle of the table - not to win anything. Their ambition was to not go down.
From 1997 I was at Lazio for three and a half years and they were lucky times - a beautiful time. The chairman did almost everything I asked. We won seven trophies and were excellent.
England has always been famous for great goalkeepers, before I came. We had good goalkeepers, but we didn't have the big world-class 'keeper, maybe.
If my style is typically Swedish, I don't know. But I never shouted in all my life at players and I never did it at my children.
With England, every time we lost I was 'not passionate.' But I tried to say we won a lot of games when I was the same.
Sir Alex Ferguson must be very high up on the list of greatest managers ever. Then there is Fabio Capello, and people forget how much Giovanni Trapattoni achieved at Inter and especially Juventus.
Sometimes things go wrong in 'football. You can lose games, own-goals, you can buy the wrong players. But you do it in the right spirit and you do it honestly. That is not how it went wrong at Notts County.
You know if you go far in the World Cup you are away for almost two months and I think it's against human nature, not to have families there.
I have a big TV screen and I sit there and watch the Premier League and I get angry sometimes - 'I'm better than that guy sitting there.' Of course, I am joking. But I analyse. I look at it technically, how they play, how they defend, how they attack, why did he change that player? That's the only way I can look at it after all these years.
I must say, the standard of football we play in League Two is better than I thought. I think, if you compared it with the fourth division in other countries, such as Italy, Germany and Spain, League Two is much, much better - and that's very positive. The intensity and the tempo is as high as the Premier League.
I had a contract with England, it was going to finish, and in football you can't really wait until your contract runs out.
I always thought I did a good job with England. But people at the time didn't think so. They had had enough of the Swedish guy only making the quarter-finals.
The big question for me is - are the players happy? Because in my mind it is all about building the right relationship with your players and creating the right atmosphere.
You don't criticise Totti in Italy. There might have been reasons to, sometimes, but you don't touch him.
You look at the way some of the big English players in the past, like Rooney and David Beckham, have been criticised and you have to ask: 'What do you want these players to be?'
I loved managing England more than anything but there were times during those five years when I thought, 'Why did I leave Italy?' because you are criticised so much.
In Italy, so long as you are not criminal, they couldn't care less about your private life. It's when you lose a football match that they criticise you - a lot.
When you go to a World Cup, the whole nation should be behind the team - and then the team have to play their part, too.
Yes, England lost to Iceland at Euro 2016 but you need to look at what Iceland had, as well as what England didn't. Maybe Iceland were not technically strong but they looked very strong together and England were not the only ones surprised by them.
My parents would make the journey across the border to Norway to buy butter and flour, staples that were cheaper there than in Sweden.
To leave a job with a bad result is, I think, the worst thing in life to do. They will always remember you as a loser.
No-one wants to finish a job badly. If you know that you are going to finish your job in six months, then you want to finish well.
The greatest barrier to success is the fear of failure.Collection: Inspirational
