Our junior national teams feature increasing numbers of kids from immigrant backgrounds, but who have grown up in Germany. Their roots are elsewhere, but they feel German. They draw on two cultures, and I believe that's been a real and visible factor in the football we've been playing. One of the best and abiding images was Cacau, a Christian with Brazilian roots, celebrating a goal with Mesut Ozil, a Muslim from a Turkish background. Ozil jumped on to Cacau's shoulders, and they gazed up into the stands, both wearing Germany shirts. It was wonderfully symbolic.
