English clubs still over the moon (8)
I believe the answer is:
ecstatic
'over the moon' is the definition.
(I've seen this before)
'english clubs still' is the wordplay.
'english' becomes 'e' (abbreviation).
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'still' becomes 'static' ('static' can be a synonym of 'still'**).
'e'+'c'+'static'='ECSTATIC'
(Other definitions for ecstatic that I've seen before include "Emotionally exalted" , "in seventh heaven" , "Jubilant" , "Showing great delight" , "high!" .)
