Manage to get calm cop upset - sort of (10)
I believe the answer is:
accomplish
'manage' is the definition.
(I've seen this before)
'calm cop upset sort of' is the wordplay.
'upset' is an anagram indicator.
'sort of' becomes 'ish' (I've seen this in other clues).
'calm'+'cop'='calmcop'
'calmcop' is an anagram of 'accompl'.
'accompl'+'ish'='ACCOMPLISH'
'to get' acts as a link.
(Other definitions for accomplish that I've seen before include "carry out" , "Achieve successfully" , "manage" , "Finish" , "Perform" .)
