Exercise before game for World Cup team, perhaps (4)
I believe the answer is:
peru
'world cup team perhaps' is the definition.
'exercise before game' is the wordplay.
'exercise' becomes 'pe' (Physical Education).
'before' is a charade indicator (letters next to each other).
'game' becomes 'ru' (rugby union).
'pe'+'ru'='PERU'
'for' acts as a link.
(Other definitions for peru that I've seen before include "Machu Picchu country" , "Mario Vargas Llosa's native land" , "Country of Lima, Cuzco and Paddington Bear" , "Homeland of Paddington Bear" , "Land of the Incas" .)
