'manager in association' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'shattered old cup record' is the wordplay.
'shattered' is an anagram indicator.
'old' becomes 'o' (abbreviation as in OT - Old Testament).
'o'+'cup'+'record'='ocuprecord'
'ocuprecord' anagrammed gives 'CO-PRODUCER'.
