Son and his mates playing in drives (5)
I believe the answer is:
spurs
I believe this is a double definition.
'son and his mates playing' is the first definition.
(Son Heung-min plays for Tottenham Hotspur FC)
'drives' is the second definition.
(spur can mean to drive something on)
'in' is the link.
(Other definitions for spurs that I've seen before include "One side of London" , "Gives encouragement to" , "incentives" , "Kicks out" , "is stimulating" .)
