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.

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.

I think you have to be grateful to those who have helped you.

Messi is the best in the world. Cristiano is a goalscorer. Messi is more taltented, more complete, tactically and footballwise. Cristiano isn't doing those runs anymore like at United. Messi takes more part in the game, I'd always prefer him in my team.

If one day I have to leave Barcelona, probably the first thing I will look into is Arsenal

I've had a couple of years where injuries have not let me develop in the way I wanted. When I was 21, after the European Championship, I had more injuries. Everything has been less continuous and it has cost me more progress. Continuity is what got me where I am.
