Footballer round B&B in Little Rock? (6)
I believe the answer is:
pebble
'little rock?' is the definition.
(I've seen this in another clue)
'footballer round bb' is the wordplay.
'footballer' becomes 'pele' (Brazilian footballer Pele).
'round' is an insertion indicator.
'pele' going around 'bb' is 'PEBBLE'.
'in' acts as a link.
(Other definitions for pebble that I've seen before include "Smooth little stone" , "Small, round stone" , "Little rock" , "Small roundish stone" , "'Small, rounded stone (6)'" .)
