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.

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

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

Best defender I have played against? Carles Puyol

Did you used to play for Barcelona? Because that's not Barcelona football.

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.
