Nordderby
The Nordderby or North derby is a match between Hamburger SV and Werder Bremen, the two most successful and popular clubs in Northern Germany. The game was first contested in 1927 with HSV recording a 4-1 away win. Since the founding of the Bundesliga in 1963, the match has been held twice every season, except in 1980–81, because Werder had been relegated to the 2. Bundesliga in the previous season. To date, 146 games have been contested with Werder holding a slight lead of 55 wins to HSV's 50. 41 games have ended in a draw.
