Rehhagel popularized the phrase "kontrollierte Offensive" (controlled offence). He prefers a grass-roots approach to football, stressing the importance of at least two (often also three) big, strong headers in central defence. His defensive schemes often use a dominant libero, such as Rune Bratseth, Miroslav Kadlec, or Traianos Dellas. In defence, Rehhagel usually prefers robustness and height over footballing abilities (the most notorious example being Ulrich Borowka). In the period of all-round, fluid defence, many have criticized this as dated and anachronistic, but Rehhagel replied that his success makes him right.
