At a club like Chelsea, they have the money to buy world class strikers like Diego Costa, and there's also that pressure to win trophies. I just have to stick with it, be patient, and hopefully my rewards will come.
I do understand Chelsea are a big club, and there is always pressure on managers to win games and trophies. So I understand they might not be willing to take a chance on someone at a bigger club.
I would never regret joining a club like Chelsea, and hopefully I will be a long time at Chelsea.
Diego Costa is a good example. He's doing very well, and he's arguably one of the best strikers in the world, so I have to see what he does and add it to my game.
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 have always pointed out in many interviews that it is my dream to manage a world-class club and win trophies. Bayern are among these top clubs, but there's also a few more.
The goal is to win. It's not about making money. I have many much less risky ways of making money than this (buying Chelsea football club). I don't want to throw my money away, but it's really about having fun and that means success and trophies.
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.
Chelsea is a very demanding club. They need to be in the Champions League and they need to win trophies because that is what the club has been doing for some time.
Diego Costa is Diego Costa. He scores goals. He is an animated character and he is a big personality.
Chelsea is a massive club, you aim to win the Premier League or are challenging for trophies with the aim to win everything.
Neymar and Hazard are amazing talents, but the player who gave me most trophies was Diego Costa.
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.
When you get a little older, you think, I'd like to make a little money and stick it away or buy a place - or win the world championship.
I had always worked to get to a club like Chelsea and start winning some trophies and doing what I have got to do.
I have won the Champions League, won the FIFA Club World Cup, the FA Cup, the Italian Super Cup, the Spanish league twice, nine trophies, all the trophies you can win at club level.
It was important for me, when I left a club like Liverpool, to one, have a breather, but then my next job, I needed pressure. And there's a pressure at Celtic. It's a huge club; there's an expectancy to win every game.
