Jupp Heynckes - "Osram"

"Osram"

Heynckes' face is known to redden noticeably when he is under stress or in a generally agitated state, especially as a manager on the sidelines during a match. This has earned him the nickname "Osram" (in reference to a German lighting manufacturer). Rudi Gores is said to have first used this moniker to describe Heynckes. Later, the nickname became universally known among German football aficionados and has been used by the media as well.
