Next to a cattle farm in a small town in northwest Germany, Keller, the starting goalkeeper for the United States World Cup team lives with his wife, two children and Rufus, a white Maltese, in a 1,000-year-old renovated castle. His renovated four-floor kingdom has two towers, a moat and a chapel. Instead of a dungeon, the basement has a spa with pool, a Jacuzzi and a steam room.
