Supporter on football pitch to attempt a record most initially ignored (8)
I believe the answer is:
goalpost
'supporter on football pitch' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'attempt a record most initially ignored' is the wordplay.
'attempt' becomes 'go' (go is a kind of attempt).
'record' becomes 'L-P' (abbreviation for long play record).
'initially ignored' means to remove the first letter.
'most' with its initial letter taken away is 'ost'.
'go'+'a'+'lp'+'ost'='GOALPOST'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for goalpost that I've seen before include "Upright with net attached" , "one unfairly moved" , "One of four supporters at ends of pitch" , "woodwork" , "One propping up the bar" .)
