Cheers after most of football team scrap (4)
I believe the answer is:
iota
'scrap' is the definition.
(I've seen this before)
'cheers after most of football team' is the wordplay.
'cheers' becomes 'ta' (I've seen this in other clues).
'after' is a charade indicator (letters next to each other).
'most of football team' becomes 'io' (I can't explain this - if you can you should believe this answer much more).
'ta' put after 'io' is 'IOTA'.
Can you help me to learn more?
(Other definitions for iota that I've seen before include "'Very small amount, jot (4)'" , "Trace" , "Foreign character" , "The smallest possible amount, or the Greek i" , "Smidgeon" .)
