Argue about being placed in a disorganised side (7)
I believe the answer is:
dispute
'argue' is the definition.
(disputing is a kind of arguing)
'being placed in a disorganised side' is the wordplay.
'being placed' becomes 'put' (I've seen this in other clues).
'in' is an insertion indicator.
'a disorganised' indicates anagramming the letters.
'side' with letters rearranged gives 'dise'.
'put' put within 'dise' is 'DISPUTE'.
'about' is the link.
(Other definitions for dispute that I've seen before include "Altercate" , "Quarrel over rights" , "Question or deny accuracy or validity" , "conflict" , "Argue about (something)" .)
