Bloomers made by footballers about middle of final (8)
I believe the answer is:
knickers
'bloomers' is the definition.
('knickers' can be a synonym of 'bloomers')
'footballers about middle of final' is the wordplay.
'footballers' becomes 'kickers' (kicker is a kind of footballer).
'about' indicates putting letters inside.
'middle of final' becomes 'n' (I can't explain this - if you can you should give a lot more credence to this answer).
'kickers' placed around 'n' is 'KNICKERS'.
'made by' acts as a link.
Can you help me to learn more?
(Other definitions for knickers that I've seen before include "Drat!" , "Panties" , "Female undergarment" , "Underpants" , "Underwear - oh dear!" .)
