In a match, goalie who has grouse to nurse (10)
I believe the answer is:
gamekeeper
'who has grouse to nurse' is the definition.
(a gamekeeper might look after grouse)
'in a match goalie' is the wordplay.
'in a match' becomes 'game' (I can't justify this - if you can you should believe this answer much more).
'goalie' becomes 'keeper' (I've seen this in another clue).
'game'+'keeper'='GAMEKEEPER'
(Other definitions for gamekeeper that I've seen before include "One raising birds for shoot" , "Occupation of Lady Chatterley's lover" , "who once poached?" , "who will encourage others to take shots" , "might be one of Rangers" .)
