A German director is displaced (7)

I believe the answer is:

manager

I'm a little stuck... Click here to teach me more about this clue!

'a german director' is the definition.
'manager' can be an answer for 'director' (synonyms). I am unsure of the 'a german' bit.

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for manager that I've seen before include "Boss" , "Controller of resources" , "One running a shop, industry etc" , "who sits on the bench?" , "Person in charge of staff" .)

I've seen this clue in The Irish Independent.
