Individual watching cricket side β attractive person (8)
I believe the answer is:
onlooker
'individual watching' is the definition.
(onlookers watch things)
'cricket side attractive person' is the wordplay.
'cricket side' becomes 'on' (cricket term, on or leg side).
'attractive person' becomes 'looker' (I've seen this before).
'on'+'looker'='ONLOOKER'
(Other definitions for onlooker that I've seen before include "He's not involved - just observing" , "Spectator" , "One who watches without becoming involved" , "One observes" , "Non-participant" .)
