#4 Ernst Happel (Feyenoord and Hamburg)
Ernst Happel started his professional playing career at Rapid Wien at the age of 17. He was also chosen in Rapid's team of the century in 1999.
After retiring as a player, Happel went on to become one of the greatest coaches of all-time. He won the league title in four different countries. He also guided two different clubs to victory in the European Champions Cup (now the UEFA Champions League).
Happel won his first ever European Championship with Feyenoord in the 1969-70 season beating Celtic 2-1. He won the European Cup again in 1983, 13 years after the triumph with Feyenoord, this time Hamburger SV, defeating Juventus 1-0 in the final in the 1982-83 season.
Happel died of lung cancer in 1992 at age 66. In the wake of his death, the biggest football stadium in Austria, the Praterstadion in Vienna, was renamed Ernst-Happel-Stadion.
