A club brawl recalled — such a shambles! (8)
I believe the answer is:
abattoir
'such a shambles' is the definition.
(shambles could historically mean a slaughterhouse)
'a club brawl recalled' is the wordplay.
'club' becomes 'bat' (as in sporting equipment).
'brawl' becomes 'riot' (I've seen this in another clue).
'recalled' says the letters should be written in reverse (to recall can mean to bring something back).
'riot' written backwards gives 'toir'.
'a'+'bat'+'toir'='ABATTOIR'
(Other definitions for abattoir that I've seen before include "Animal slaughter-house" , "building where blood is shed" , "place where animals die" , "I tar boat (anag)" , "It might make a killing" .)
