Looking peculiar in soccer gear? Every chance! (5,4)
I believe the answer is:
short odds
'every chance' is the definition.
(both can mean a good chance of something happening)
'looking peculiar in soccer gear?' is the wordplay.
'looking peculiar' becomes 'odd' (odd-looking).
'in' is an insertion indicator.
'soccer gear?' becomes 'shorts' (part of a soccer kit).
'odd' going inside 'shorts' is 'SHORT ODDS'.
(Other definitions for short odds that I've seen before include "An almost even chance" , "What favourites are at the bookmaker" .)
