Front put up by a soccer rebel? (6)
I believe the answer is:
Here is my best explanation:
'front' is the definition.
(facade is a kind of front)
'put up by a soccer rebel?' is the wordplay.
'put up' is a reversal indicator.
'by' is a charade indicator (letters next to each other).
'soccer' becomes 'f' (I can't justify this - if you can you should believe this answer much more).
'rebel?' becomes 'cade' (I've seen this before).
'a'+'f' is 'af'.
'af' back-to-front is 'fa'.
