Man contrarily supporting rebel leader, unknown where I live (4,3)

I believe the answer is:

chez moi

I'm a little stuck... Click here to teach me more about this clue!

'live' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'man contrarily supporting rebel leader unknown where i' is the wordplay.
I cannot really see how this works, but
'man' could be 'che' and 'che' is found within the answer.
'unknown' could be 'z' (algebra) and 'z' is located in the answer.
'i' is found in the answer.
The remaining letters 'mo' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
