One-nil up, I help distraught Reds fan? (9)
I believe the answer is:
oenophile
'reds fan?' is the definition.
(fan of red wine - oenophile means a lover of wine)
'one-nil up i help distraught' is the wordplay.
'nil' becomes 'O' (O resembles 0).
'up' is a reversal indicator (in down clue: letters go upwards).
'distraught' is an anagram indicator (an unsettled or upset order of the letters).
'one'+'o'='oneo'
'oneo' backwards is 'oeno'.
'i'+'help'='ihelp'
'ihelp' anagrammed gives 'phile'.
'oeno'+'phile'='OENOPHILE'
(Other definitions for oenophile that I've seen before include "Drink lover" , "Lover of wine" , "port authority" , "wine I enjoy" , "Wine buff" .)
