Under Pep Guardiola, it's hard work. For me, Guardiola is one of the best coaches I've ever met. He's incredibly clever and tactically really good, and he knows how to speak to us, how to motivate us, and that's what it is like.
Over the years, you get better at timing because you've been through the situations thousands of times. The ball goes over your head; he passes you on the right, left. Eventually, you just know what you have to do.
You mostly defend with your head, always reacting to the movement of opponents and teammates. I had to become more aware of that, play with much more consideration, the way you drive a car: you always need to look left, right, and the rear mirror to see what's going on around you.
You meet somebody on a bus or something, and they say, 'Thank you for the World Cup; it was so good to see,' and stuff like this - it's funny.
My motivation is that I try to get myself to a certain point, and I want to win as much as I can in my career.
I wanted to set new goals, because if you say, 'Oh, I'm world champion,' you don't grow, and you don't keep your level.
