Oddly, more fan than chief (7)
I believe the answer is:
foreman
'chief' is the definition.
(I know that foreman is a type of manager)
'oddly more fan' is the wordplay.
'oddly' indicates an anagram.
'more'+'fan'='morefan'
'morefan' anagrammed gives 'FOREMAN'.
'than' acts as a link.
(Other definitions for foreman that I've seen before include "Gaffer, overseer" , "Fellow in charge" , "spokesman" , "Gaffer, boss" , "Male supervisor" .)
