1999/00: Lizarazu slapped Matthäus in training. 1990s: Ziege and Bernardo separated in training. 1980s: Pfaff smacked goalkeeping rival Aumann during press-ups.
Most serious: Champions League semi-final vs Real Madrid, April 2012. Ribéry gave Robben a black eye in the dressing room after a free-kick row on the pitch. Fine: €50,000.
