My first trophy in France was the Young Player of the Year. I was 17. Chelsea is not just one player. It is not only me. We have signed a lot of players. Now we have some good signings like Cesc Fabregas and Diego Costa.
There are many clever contractual ways to let a young player continue his career elsewhere while still having first option to bring them back in future. Contracts can include a buyback clause such as Barcelona had with Cesc Fabregas, or a sell-on clause where the development club benefit financially from all the work invested in the young player.
We have a psychologist at Chelsea who goes around seeing the loan players. He said every top, top player has a dark side. So someone like Diego Costa sometimes oversteps the mark. But you can see he plays on the edge. He said I had to develop that. It's not natural for me to be like that.
Atletico players have always been characterised by this kind of player in attack like Fernando Torres, Sergio Aguero, Diego Costa, and Radamel Falcao.
The best player I ever played with is probably Cesc Fabregas. I only got to play with him for a year before he went back to Barcelona, but I learned so much from him - the way he knew what he was going to do with the ball before he got it and his passing - and he scored goals.
Diego Costa always gives us physical and moral strength. He is a very important player for the character he transmits to the team, and his potential as a football player.
When I was at Hamburg, 17 or 18, Ruud van Nistelrooy signed, and he helped me a lot. He saw my first training session, and he talked to me. He told me I was a good player. He gave me confidence, and I want to thank him for that.
Jorginho is really suitable to the way I like to play. He is a player that has many good sides to him. He wants to work hard, and he's very fast in moving the ball, which is important for us, although there is also Cesc Fabregas, who has the same potential as Jorginho.
I play with some talented players like Cesc Fabregas, Nemanja Matic and Nathaniel Chalobah. They have different styles and I can learn from everyone.
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.
Certainly when you're surrounded by top-class players, like Cesc Fabregas, Eden Hazard, all of them, you only can make progress in a situation like that.
I've always been clear - I feel good at Chelsea. Every week, I repeat the same on PSG. It's a big team but an inferior league. I don't want to return to France, because I've won everything over there - the league title, cup, best player, best young player.
I have good friends at Chelsea. I talk sometimes with Eden Hazard, Gary Cahill, Cesc Fabregas but with all of them they are my good friends and they are good guys.
Neymar and Hazard are amazing talents, but the player who gave me most trophies was Diego Costa.
A good player is a good player, it's just that we cannot afford signings that do not work.
Didier talks to all of us. Not just with me, but with all the attacking players. He has scored so many goals for Chelsea. But now he pushes the younger players. He is fantastic. A fantastic player, and a fantastic person.
It is one of my biggest regrets that Niall Quinn was not here during my time... I felt he was an intelligent player. It would have been a good combination with Thierry Henry. What I like with Quinn is if you look at the player who played next to him, he always scored 40 goals because he had a hand for his head and he just put the ball where you were. He was a team player. A top-class player makes other players look good and he had that player.
