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

Carles Puyol is a Barcelona legend. He could have been playing every two weeks but he has shown dignity until the end.

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.

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.

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.

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