Good friend on pitch, everywhere (8)
I believe the answer is:
globally
'everywhere' is the definition.
(I've seen this in another clue)
'good friend on pitch' is the wordplay.
'good' becomes 'g' (abbreviation).
'friend' becomes 'ally' (an ally is a friend or supporter).
'on' is a charade indicator (letters next to each other).
'pitch' becomes 'lob' (both can mean to throw).
'ally' put after 'lob' is 'lobally'.
'g'+'lobally'='GLOBALLY'
(Other definitions for globally that I've seen before include "Across the whole world" , "Worldwide" , "all round the world" , "Universally" .)
