Real Madrid stint: "When you are in charge at Real Madrid, you have to be able to accept that it is not just a sporting club, it's also very political. And also to what extent you are willing to allow people who, in my opinion, do not have sufficient knowledge of football interfere... If a coach lets somebody who has no understanding of the game interfere, or allows themselves to be weakened by the criticism which originates from the political side, the sporting side or even for personal reasons, then I don't think that person is suitable for the job.
