It's very difficult to reach World Cup and Champions League finals and I want to experience those things again.
On a tactical level the defensive midfielder in a 4-3-3 formation is just about the most demanding position there is.
Every manager is different in one way or another, but what stays the same is coaching Barcelona players - players who want the ball, who want to be protagonists on the field - so each manager who's been here has been able to take advantage of that, and, luckily, I feel we've become more complete because of it.
I've always said that I won't be a Barcelona player for 20 years with a secondary role. The moment that I feel my ambition is fading or that I am not able to deliver physically, I will step aside and leave feeling privileged and content of what I gave to the club.
It's the Champions League that really gets the Barcelona fans buzzing.
Stadiums are full, pitches are good, the press is different, people are different, the football culture is different. Everyone talks highly of England and I'd like to experience it one day. You see more space, more opportunity to enjoy your football. It's more physical, more intense, but I think I'd be comfortable.
My team-mates appreciate that I do the dirty work and I know it is necessary.
If there's a problem, I prefer to have to swallow that myself than force a team-mate to do so. I think about them because in my position that is what your job consists of.
