Misfit team manager is one using English left back (5)
I believe the answer is:
trope
'misfit team manager is one' is the definition.
I can't judge whether this defines the answer.
'english left back' is the wordplay.
'english' becomes 'E' (abbreviation).
'left' becomes 'port' (left side of a ship - opposite of starboard).
'back' says the letters should be written in reverse.
'e'+'port'='eport'
'eport' written backwards gives 'TROPE'.
'using' acts as a link.
Can you help me to learn more?
(Other definitions for trope that I've seen before include "literary effect" , "Figurative use of a word or expression; motif" , "ironical expression" , "in a manner of speaking?" , "Figure of speech - or pet (anag)" .)
