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

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

He is a very complete, spectacular footballer. He always fights for the ball and tries to lose his marker to help his team-mates - either to defend or to have a shot on goal. For any football player in the Premiership, Scholes is a player you want to emulate. I would happily end my career with the medals that Scholes has. I am young and I hope that I will be able to surpass him - but it is not going to be easy.

You have to fight for your dream, but you also have to feel fortunate for what you have.

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.

Best defender I have played against? Carles Puyol

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.
