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.

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.

I believe that the Premier League is the best league in the world, and having played in the Premier League for such a long time, it is to my advantage, and I know what to expect.

I'm so focused on the game that I hardly understand what the people sing or shout or what they do.

Iker Casillas is one of those keepers who always seems to be at his best in the really difficult games when he has hardly got anything to do but reacts when needed in those emergency situations.

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.

I understood I had to be good at school so I could play football in my free time. Usually, by the time I came home from school, I already had all my things ready for the next day, so I could put my bag on the side and go straight out to play football with my friends!

It's always good to have the right call in the end.

It's always difficult to say if anyone is in the best form of their career.

Unfortunately, money is very important in this world we live in, but it is up to every individual to deal with it.

You win the way you have to.

I always like to do things the right way.

Football is a collective sport, but goalkeeping is an individual sport.

If you take the autobiographies of great sports people, they are almost always the same. They start with zero; they are always ambitious, know what they want to do in life, and have the confidence to do it.

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.

You can be the best manager in the world, but if the players don't trust you, it will never work.

Who is the best goalkeeper in the world? It's always hard to choose because there are so many great goalkeepers.

In big clubs, you always have competitions for places.

Obviously, every player wants to keep their spot in the starting line-up, and I'm the same.

True fans will appreciate what I've done and the legacy I've left.

There are some people who have left me negative messages, but they aren't true Chelsea fans.

With goal-line technology, there are plenty of results that could be changed.

Unfortunately, the manager is always the one who gets under pressure the most.

You need to defend as a team to defend well.

Sometimes, when you have a young team full of enthusiasm, they don't feel any pressure; they just play.

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.

I think it's very useful when you want to be the team who create. You need to create this superiority at the back when you build up using the goalkeepers.

Sometimes, if a striker is not scoring as many goals, they can still be in good form.

Every time you can score more goals you should try to do so.

You can't control games for 90 minutes; there will be moments where the opponents will show their quality.

Everybody makes mistakes, and I am a human being.

Football is played by 11 players, and unfortunately, every time, it happens that some do well, and some do worse.

In a way, the manager plays as big part, but you, as a player, are on the pitch. He cannot make you run if you don't want to; he cannot make you make the right decision in the heat of the moment.

In football, you only work for the things you can control. You cannot control the outside world: you can only control your preparation; you can only control your performances.

Do I want to play every game? Yes, I want to play every game. But I also understand it's impossible.

Sometimes you need to make sure that, no matter how you do it, you win the games.

When you are going for every trophy, it is always good to have as many points as early as possible in the Champions League, and then you can concentrate on the league and the Carling Cup.

Every summer at a club is important because you have some changes in the squad.

I like people who tell you what they think straight away instead of going around in circles.

I speak five languages, which actually makes it easier when you join a new team. You can settle much quicker because you can help team-mates much faster and better. People need to be careful around me, though - I can understand everything.

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.

If a team concedes a goal, then the first question is always of the goalkeeper.

I played tennis a lot when I had the skull injury. For the first two months of my preparation, it was all I could do. It is a great sport for me because it helps my hand-eye coordination, and you need quick feet, which is a good exercise for a keeper.

I had a depressed skull fracture. A few pieces of bone went in quite deep; that was the biggest danger.

Once you're on the pitch, you play for your team, and you want to win. During the year, you can play against friends - you can play against big friends and close friends - but once you are on the pitch, this friendship goes away, and you just focus on winning the game.

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.

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.

All managers have a different playing style and football philosophy. What's important for players is being able adapt to those different styles.

Once the surgeon said the skull is strong enough with the helmet on, I decided to return to training with the team.
