Player in red? (4-6)
I believe the answer is:
left winger
This clue is a double definition.
'player' is the first definition.
(I know that left winger is a type of midfielder)
'red?' is the second definition.
(I know that left-winger is a type of red)
'in' acts as a link.
(Other definitions for left winger that I've seen before include "red" , "Team player" , "one of the Reds" , "Footballer" , "Commie" .)
