Great performance against clubs ... (8)
I believe the answer is:
gigantic
'great' is the definition.
(I've seen this before)
'performance against clubs' is the wordplay.
'performance' becomes 'gig' (I've seen this before).
'against' becomes 'anti' (I've seen this before).
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'gig'+'anti'+'c'='GIGANTIC'
(Other definitions for gigantic that I've seen before include "Of very great size" , "Fantastically great" , "walloping" , "Thumping" , "Huge, enormous" .)
