I always like to remember the year 2008, when we had an amazing offer from Chelsea for Franck Ribery. From that day on, the whole world of football knew nobody can buy a Bayern Munich player against the will of Bayern Munich.
I know Spain football very well, because I've always been interested in it, even after I left Spain.
I played at the highest level, so I know what kind of things go through a player's mind and how he might behave, what patterns will crop up in the day-to-day routine.
I was always a great admirer of Zizou the player, but now I also admire him as a coach. I like how calm he is. This shows me that he's not showcasing for the public or the camera. He's a top trainer.
We need to be aware of what we need to do at every moment... and we have to manage the game; that's the art of a great team.
The Champions League is special. You play at a higher level, so you have to be very focused and have greater motivation.
