Demanding English team win round noon (7)
I believe the answer is:
exigent
'demanding' is the definition.
(similar in meaning)
'english team win round noon' is the wordplay.
'english' becomes 'e' (abbreviation).
'team' becomes 'xi' (eleven, a football team).
'win' becomes 'get'.
'round' means one lot of letters goes inside another.
'noon' becomes 'n'.
'get' going around 'n' is 'gent'.
'e'+'xi'+'gent'='EXIGENT'
(Other definitions for exigent that I've seen before include "Urgent and exacting" , "Pressing and urgent" , "Urgent and taxing" , "Pressing; demanding" , "Exacting, requiring much" .)
