Unintentional consequence of team acquiring property perhaps (4,6)
I believe the answer is:
side effect
'unintentional consequence' is the definition.
'side effect' can be an answer for 'consequence' (side effect is a kind of consequence). I am not certain of the 'unintentional' bit.
'team acquiring property perhaps' is the wordplay.
'team' becomes 'side' (both can mean a sports team).
'acquiring property perhaps' becomes 'effect' (I am not sure about this - if you are sure you should believe this answer much more).
'side'+'effect'='SIDE EFFECT'
'of' is the link.
Can you help me to learn more?
(Other definitions for side effect that I've seen before include "Unwanted consequence" , "Corollary of" , "Incidental result" , "Fallout" , "Secondary result of, eg, drug" .)
