I've always been following Chelsea and every time I came to London I would try to see a Chelsea game and see how the team was doing because it's been my dream to come to play here.
I have been at Chelsea for a lot of years. I have played in the Premier League, the Champions League, it is a kid's dream to play for Chelsea. I have moved on, who knows I might one day go back to Chelsea.
When I played against Chelsea, there was always a big motivation because it was a special game; it was always one of the biggest games of the season. This is one of the reasons why I wanted to join Chelsea: because I want to be part of this kind of team.
I always watch Chelsea games when I have the time and step-by -step, game-by-game, Chelsea is growing. I speak with Branislav Ivanovic, my friend and international team-mate a lot, a few times each month, so I know everything about the club.
Every game, I have to make the best decision. I repeat: my players must be happy to stay in Chelsea and to play for Chelsea and to play for our fans. They must be happy if they start the game or if they stay on the bench and come on.
You look at a club like Chelsea, and you know it won't be easy to get into that team. Sometimes you have to go away, play regular first team football, and show Chelsea that you are ready to play for them.
The main reason to come to England and Chelsea was to play with a great team. Money and the chance to live in a city like London are additional factors.
When I see somebody, I try to beat him on both ends of the floor. It's the game within the game that you've always got to win. That's always been my mindset. That's how I was taught how to play the game. That's how I learned. And that's what I enjoy.
When I was little, my dream was to come and play in the Premier League. So when Chelsea came in, I said yes straight away.
I wanted to finish at the top of the game and on my own terms. I thought it was the perfect time at the World Cup and to go out at Chelsea. Chelsea and England were immense in how they have supported me in that transition.
At 21, Real Madrid or Barcelona would have been more difficult for me. If I play well enough at Chelsea, I could win my place in the starting team, and my priority is to play.
I'd been at Chelsea for a while and progressed quite quickly until I got to the first team, and then it was different. I was used to playing every minute of every game, but when you get to that level, the step up is massive. There are world-class players in front of you, and no matter how talented you are, breaking in is difficult.
I'd first come to Chelsea from Kosice and, for me, that was a dream. It's not easy making that move. I was maybe the first player to come from Slovakia to a club like Chelsea, who normally buy players from Holland, Spain, Italy, Portugal.
I've always said I wanted to play in England. There was a struggle between Chelsea and United, but according to me, Chelsea has the best project.
I gave my first interview when I arrived at Chelsea in 2004, and I had said that it had been my dream to play for one of the best clubs in the world and in the best league in the world - this came true, and I am very pleased my dream will last.
I came back to Chelsea to stay. When I took my decision to come back here from Paris, it was to win the Premier League and to do something again with Chelsea, so I am very happy here.
I would never regret joining a club like Chelsea, and hopefully I will be a long time at Chelsea.
