That hurt, Glaswegian hooligan admitted (5)
I believe the answer is:
owned
'admitted' is the definition.
(own can mean to admit or acknowledge)
'that hurt glaswegian hooligan' is the wordplay.
'that hurt' becomes 'ow' (exclamation of pain).
'glaswegian hooligan' becomes 'ned' (Scottish term for a hooligan).
'ow'+'ned'='OWNED'
(Other definitions for owned that I've seen before include "Possessed; admitted" , "to oneself?" , "Confessed" , "Acknowledged" , "fully paid off?" .)
