Arsenal is a team who challenge for the top and definitely match my ambitions and personal motivation.
I had a depressed skull fracture. A few pieces of bone went in quite deep; that was the biggest danger.
Once the surgeon said the skull is strong enough with the helmet on, I decided to return to training with the team.
Now the ambulance is always ready; the paramedics are always ready. People in the crowd can get help without risk. If you look at the Fabrice Muamba case, this is what helped save his life - the paramedics are there.
Sometimes in the Premier League, you are in a game where you can't play nice football because you just wouldn't win it.
I'm amazed people talk about my helmet - saying it makes me feel psychologically better. I would love to play without it, but I'm not allowed to by the doctor. As long as I'm told by the doctor I'm running too much risk to play without it, I'll play with it. There's no other way for me.
Unfortunately, money is very important in this world we live in, but it is up to every individual to deal with it.
You have to have respect for money, but sometimes you get people who stop thinking about their career, and for them, it is just a case of saying, 'Look at me. I have a lot of money now, and I can do whatever I want.' I wouldn't do that.
Buffon may be a bit smaller, but he has everything that you want from a great goalkeeper. He relays his confidence to his defence, and they feel that they have a great keeper behind them. Everybody can make mistakes, but his consistency level is amazing. You never see him have a bad game.
I don't do nervous, really. You always have to respect your opponent, respect the game of football, and be 100 per cent focused.
The connection between the Soviet Union and Czech people - or Czech politicians - was very big. It was like a model country for us. But it wasn't the best model, so a lot of Czechs don't like to speak about Russia or the Soviet Union.
When I was in high school, I started learning English as my second foreign language, but my level of English at that time was very average.
I speak all my languages basically every day with the people in the dressing room, and it's a pleasure to be able to do so. On the pitch, if it's a group of players I'm trying to communicate with, then I use English because you need to make sure everyone understands what you are saying.
My favourite language, actually, is Czech, just because it's so colourful. We have so many combinations, words, and expressions. I have to say there are a lot of things which you can say in Czech, but you cannot really translate, because the meaning would make no sense.
I don't like running that much, and during the off-season, I have to do it, but if I can replace it with tennis, it is better.
We won back-to-back titles in 2005 and 2006, and it was a fantastic achievement, a fantastic feeling. Once you experience that, you want to have it again.
There is always a lot of pressure at Chelsea, but we are used to this and have to make sure we keep winning games.
Wenger and Mourinho are different, but there is one thing they have in common, and that is that they do not like defeats. And I think this is the driving force behind the success of both of them.
I would like to be a manager, to organize everything in training, see if my philosophy could work, and give it to the team.
Obviously, as long as I enjoy it, I'm fit, and have the desire to work 100 per cent every day with the same motivation, then I want to play.
You have to be consistent in your work, consistent in your performances, because, if not, then you might not have as many games as you would like. Less games you play, then less chances to have a clean sheet.
Who is the best goalkeeper in the world? It's always hard to choose because there are so many great goalkeepers.
Chelsea has grown in my heart, not just because of my team-mates and all the people that work for the club but also because of their fantastic fans.
Jose Mourinho doesn't have a magic wand, and you wave the wand, and everything goes the way you want.
His ball technique is superb, but most importantly, he can react to how the game develops. At the last possible moment in any situation, he can find the ideal solution. There are a lot of ways that Messi can finish an attack.
As a player, it's better to wait a moment for the correct call than be let down by an incorrect call.
All managers have a different playing style and football philosophy. What's important for players is being able adapt to those different styles.
Sometimes, when you have a young team full of enthusiasm, they don't feel any pressure; they just play.
It is always great to be a position like this, where you play for everything because it is so exciting.
Obviously, you have the physicality and the way the game is played in the Premier League. The goalkeeper is not as protected as in Europe or different leagues.
There are so many things that a goalkeeper coming to the Premier League has not experienced in a different league.
