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

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

Apart from Arsenal and Barcelona, I don't see myself playing anywhere else. I will definitely be going back (to Arsenal) whenever I have time to watch games and to see the guys… and if there is one place to go back to (to play), it is Arsenal for sure.

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.

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

I am really proud to HAVE been an Arsenal player.

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.
