In best clubs one creates talking point (5)
I believe the answer is:
topic
'talking point' is the definition.
(I've seen this in another clue)
'in best clubs one' is the wordplay.
'in' is an insertion indicator.
'best' becomes 'top' (top can mean the very best).
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'one' becomes 'I' (Roman numeral).
'top'+'c'='topc'
'topc' going around 'i' is 'TOPIC'.
'creates' is the link.
(Other definitions for topic that I've seen before include "Subject (for conversation, etc)" , "Matter for an argument" , "Question" , "might this be hot?" , "A subject for conversation or debate" .)
