If I ever wear a Chelsea shirt, you have permission to kill me.

I do feel that I have unfinished business in the Premier League and now is the right time to return. I considered all the other offers very carefully and I firmly believe that Chelsea is the best choice. They match my footballing ambitions with their hunger and desire to win trophies.

If I could reincarnate as another player, I might want to reincarnate as Thierry Henry at the top of his game.

Hard work does not guarantee success, but no work guarantees failure.

If one day I leave Arsenal, I will never sign for another English team. Quite sure.

My mum has always said I am too hard on myself. But I have always been like that and it has always helped me. After matches I focus only on what I did wrong. Never what I did well.

I am an Arsenal player and I don't think about anything else. I'm not going to say no to anybody, nor am I going to say yes to anybody. I did not say that I was going to leave Arsenal to go to Barcelona, because equally Barcelona doesn't want me.
