“When I go to a new club, I always want to keep one coach from the existing staff. At Bayern that person was Herman Kerland, who is still working there now under Pep Guardiola. I wanted to know who was coming through the youth system. I always want to know that. He is the man who said to me: "Muller, Badstuber and Alaba. These are the players." So I let them train with the first team, I observed them – and then I decided where they were going to play.”
