Club: Hamburger SV
Growth type: Standard/Lasting
Kaltz played in the Bundesliga for Hamburger SV and 13 times (1 goal) for FC Mulhouse in Ligue 1 after initially joining Mulhouse league rivals Girondins de Bordeaux 1989. He returned to Hamburg the season after, the consequence of the relegation of FC Mulhouse from Ligue 1 at the end of 1989–90. Previously, Kaltz was forced to leave Hamburg, the club for which he had been a professional since the 1971–72 season, after the authorities (e.g. Erich Ribbeck) had decided not to go on with the contract of the long-serving full-back. Their successors lured him back from France in September 1990 to give him the chance to serve his final year as a player at his old club.
In total he played in 581 Bundesliga games for Hamburger SV, to this day remaining the second greatest total of an individual in Bundesliga history. An expert in penalties, the Hamburg fan-favourite scored 53 of his 76 goals from the spot, a record in the Bundesliga.
Kaltz was famous for his right-footed crosses, which he hit with so much spin that they curved like a banana. They were affectionately called "Bananenflanken" ("banana crosses"). He often used this technique to set up hulking striker Horst Hrubesch, who often headed them into the opposing goal. Among his many achievements, Kaltz also holds the unenviable record of scoring the most own goals in the Bundesliga, 6.
