5. Marcell Jansen – 50 goals
Marcell Jansen is a German former footballer and current president of Hamburger SV. He was well known for his accurate crossing and pace, despite his tall stature. A versatile player, he played primarily as a full back or wing back on the left flank, but could also play as a left-winger or even as a striker. Despite finishing his career at age 29, he is to this day one of the best goalscoring defenders to have ever existed.
