Clubs winning trophy (3)
I believe the answer is:
cup
'trophy' is the definition.
(I know that cup is a type of trophy)
'clubs winning' is the wordplay.
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'winning' becomes 'up' (eg being up at half time in football).
'c'+'up'='CUP'
(Other definitions for cup that I've seen before include "Sort of cake" , "Prize; vessel" , "McCarthy, Walker or Maguire" , "competition" , "'There's many a slip 'twixt ... and lip.'" .)
