As a team, you always need to show something extra in the Champions League.
Even during a sprint, I can occasionally still accelerate. I am so fit that I can accelerate during a acceleration, like making a new start.
I have lots of energy, but that doesn't happen like magic. I put in many extra hours in the gym and with the physios.
The football in Spain is more about skill and technique. Every team tries to play good football. The physical side, with plenty of running and hard tackling, plays more of a role in the Bundesliga.
We have to respect the opponents.
Van Gaal is the kind of guy who can really make individual players better.
When we are in possession, tactically, he is the best coach in the world for me. He works hard, watches a lot of games, and prepares us really well. Guardiola has the feeling for gaping spaces, and he already had that as a player.
The Champions League is very difficult - there are so many big teams in Europe, and one bad day, and you can be out.
Van Gaal is the best coach I've had. We've got a very special relationship.
I want to try to have fun as long as I can and play football at a high level. I do not know how long that will go on.
If you want to achieve something and have results and win competitions at a high level, you have to defend as a team.
When I came to Chelsea and worked with Mourinho, it was my first time abroad, so that was an important stage for me.
What I will miss the most about Guardiola? His obsession with the game and his knowledge, which makes you a better football player.
It's really amazing what Pep Guardiola has done at Man City.
The appreciation between Bayern and I has always been there, from both sides. I know what I have at this club, and I always say that.
Every league has its own culture, its own identity, and its own type of football. It's very physical in England, but technical skill comes to the fore in Spain, where everybody wants to play beautiful football. The standards are very high in Germany, too; the teams are physically strong, very disciplined, and very well organised.
Players come and go, and that goes for coaches as well.
Munich is a great city. I have lived in many cities in Europe, but I have never felt this comfortable, and my wife and children love it as well.
A backheel is good if it works, not if it disrespects the opponents.
It is important that it - sometimes there are clashes between team-mates. We need each other to tell the truth, and this is not always a positive.
