Free kick routine producing some fireworks? (3,5)
I believe the answer is:
set piece
I believe this clue is a double definition.
'free kick routine' is the first definition.
'some fireworks?' is the second definition.
(set piece can mean an exciting display)
'producing' is the link.
(Other definitions for set piece that I've seen before include "rehearsed play" , "corner, say" , "Carefully structured and practised speech - see pi, etc (anag)" , "Elaborately arranged display" , "firework display" .)
