Excellent opener from Huddersfield Town (5)
I believe the answer is:
neath
'town' is the definition.
(town in Wales)
'excellent opener from huddersfield' is the wordplay.
'excellent' becomes 'neat' (I've seen this before).
'opener from' suggests taking the first letters (I've seen 'openers from' mean this (letters which open the words are used)).
The initial letter of 'huddersfield' is 'h'.
'neat'+'h'='NEATH'
(Other definitions for neath that I've seen before include "Welsh industrial town" , "Under (poetic)" , "River" , "Town NE of Swansea" , "Welsh team" .)
