Choose the French World Cup hero? (7)
I believe the answer is:
pickles
'world cup hero?' is the definition.
I can't judge whether this defines the answer.
'choose the french' is the wordplay.
'choose' becomes 'pick' (picking is a kind of choosing).
'the french' becomes 'les' (plural form of 'the' in French).
'pick'+'les'='PICKLES'
Can you help me to learn more?
(Other definitions for pickles that I've seen before include "Vegetables preserved in vinegar or brine" , "Preserves in vinegar or brine" .)
